Versa User Manual www.teledynetekmar.com
SAFETY SYMBOLS
Never connect a ammable gas (such as hydrogen) as the gas supply to the Versa. Venting of this
gas in the standby creates an explosion hazard.
The interior of the instrument is an electrical shock hazard. Turn o the instrument and unplug the
power cord before removing the protective covers.
It is recommended that safety glasses be worn at all times when operating the Versa. Heated
sample vials are under pressure during normal operations. An inadvertent over-pressurization
could cause a vial to burst.
This instrument contains heating elements. Touching any heated zone during the operation
could cause a burn. The system’s heaters will activate when their setpoints are above ambient
temperatures. Keep all instrument panels fastened when operating the Versa.
Use extreme care when handling hot vials, particularly when unloading vials from the Versa.
Improper handling of hot vials may cause a burn.
Be alert for environmental, shock, or other hazards in the event that a vial would break. Before
cleaning up, unplug the instrument and determine the nature of the sample that has spilled. Use
extreme caution and apply the appropriate clean-up measures.
Do not over pressurize or over heat samples during operation. Extreme static pressure
build-up in a vial due to excess pressure levels or heat settings could cause a vial to burst.
When accessing the valve oven area, be certain that the valve is cool before opening the cover.
Pinch Point Hazard! Keep hands and other appendages away from the carousel and elevator
during operation.

STATIC HEADSPACE
Static Headspace is a technique used for sampling the gas phase of a sample. The technique can be used for
both qualitative and quantitative analysis. Static Headspace can be separated into three basic operations, Sample
Equilibration, Sampling and Injection. In this section of the manual the basics of Static Headspace will be described.
Sample Equilibration
The analysis is completed in a closed system making it impossible for the system to create or lose mass. When a
sample reaches equilibrium, the mass in the matrix plus the mass in the gas must equal the original mass placed in the
vial. (Refer to Equation Below)
Mass Balance Equation
MO = MG + MM
MO = Original Mass Placed in the Vial
MG = Mass in the Gas Phase After Equilibrium
MM = Mass in the Matrix After Equilibrium
The amount of mass that leaves the matrix for the gas phase is dictated by the partition coecient (K). This is a
physical constant that is directly aected by the temperature of the sample and the pressure in the vial. Assuming
that the make-up of the matrix and the volume is consistent, the pressure in the vial can be disregarded since each
vial should create approximately the same internal pressure after heating; this is called the Static Vial Pressure. If
this does not hold true for a particular set of samples, refer the Method Development Section of this manual for
further instruction. If the sample temperature is held constant for the appropriate amount of time, the system will
reach equilibrium.

CM = K*CG
CG = CM/K
K = Partition Coecient
CM = Concentration in the Matrix
CG = Concentration in the gas phase or the headspace

Since the equilibrium is a constant, Static Headspace analysis is a quantative technique. The concentration in the gas
phase is directly proportional to the original concentration in the matrix.

VV = Volume of the vial
VM = Volume of the Matrix

CO = ((CG
*VG) / VM)+ ((K*CG *VM) / VM)
CO = ((CG
*VG) / VM)+ K*CG
CO = CG((VG / VM)+ K)
VG / VM = Phase Ratio
The system’s sensitivity for an individual compound is directly aected by two factors, the partition coecient and
the phase ratio (Volume of the Gas phase vs. Volume of the Matrix). The K value can be improved by changing the
matrix conditions forcing more compound into the gas phase thus allowing more mass to be transferred on-column.
In situations where the K value is low, the phase ratio can dominate the bottom term of the concentration equation
making it possible to change the concentration in the gas phase by decreasing the gas volume in the vial. This will
result in a denser mass or higher concentration in the gas phase for injection.
Sampling
Once the vial has reached equilibrium the sample is ready to be prepared for injection. The vial is raised onto a needle
and a small amount of gas is added to the vial to pressurize it prior to sampling. Once the vial is pressurized, a solenoid
valve is opened to allow sample gas to ow through a 6-port valve and loop. The solenoid valve is then closed and the
sample gas volume is trapped in the loop.
Since the sample is a gas, it is compressible thus sensitivity is directly aected by the Universal Gas Law.
PV=nRT
P = Pressure
V = Volume
n = Number of Moles
R = Universal Gas Constant
T = Temperature
The Universal Gas Law states that the number of moles in a system is a function of the temperature, pressure and
volume of that system. The number of moles is equal to the mass in this gas system.
n= PV /RT

Therefore, the three variables, temperature, pressure and volume, have a direct aect on the sensitivity of the system.
The temperature in the Versa that would aect injection mass is the Valve Oven Temperature. The lower the temperature
used, the denser the mass of the gas in the loop. The pressure aects the sensitivity in two areas: the higher the vial
pressurization setting, the more dilution gas is added thus lowering sensitivity; while a higher loop ll pressure results in
higher sensitivity. The volume of the loop can be changed to allow for more mass to be injected on column. The volume
can be varied between the optional loop sizes of 100μl up to 5mL. The Versa is shipped with a 1mL loop.
Note: Refer to the Method Development section of this manual for further information on the eects of temperature,
pressure and volume.
Injection
Once the Sample Loop has been lled, and the GC is ready for injection and the 6-port valve is rotated. When the 6-port
valve is in the “B” position, it allows carrier gas to back ush the sample from the loop onto the analytical column. The GC
data system is started concurrently. The vial is lowered from the Platen and the sample pathway is subsequently swept
while waiting on the equilibration of the next sample to eliminate cross contamination.

volume to be swept to the GC for analysis.

SAMPLE NEEDLE
The Versa uses a 1-stage sample needle to displace sample
from the vial to the sample loop.
FLOW RESTRICTOR
The Versa uses a 100mL/min ow restrictor to provide
standby ow and pressurization ow. When the system
pressure is set to 18psig, the standby and pressurization
ow measured out the needle is approximately 50mL/min.
CAROUSEL TRAY
The 20-position carousel tray is removable from the
carousel drive assembly; the tray can be removed without
the vials.
GAS INLETS AND OUTLETS
Transfer Line
The Transfer Line is the interface between the GC and the
Versa. Carrier gas makes a passive current through the
Versa and returns unchanged to the GC through the
transfer line. GC carrier gas is typically controlled through
the GC.
Carrier Gas is helium (or nitrogen) with a high degree of
purity, used to ush volatile organic analytes through the
transfer line back to the GC. Carrier gas enters the back
of the Versa through the heated transfer line. Carrier gas
back ushes through the sample loop and carries volatile
organic analytes over to the GC.
Pressure Sample Gas Inlet
Pressure sample gas (ultra-high purity helium or nitrogen)
ows through the Versa System to pressurize the vial and
sweep clean the system between samples. The gas enters
the unit through the back panel in the blue 1/8” tubing
labeled “Pressurize Gas”. Refer to the Method Development
section of this manual to determine the proper ow rates
and pressures for your specic application.

Never connect a ammable gas
(such as hydrogen) as the gas
supply to the Versa. Venting of
this gas in the standby creates
an explosion hazard.

HEADSPACE VALVES
The Versa system has two solenoid valves in the standard
conguration. The standard valves are the Pressurization
Valve and the Vent Valve.
Pressurization Valve
The Pressurization Valve allows pressurization gas to ow
through the needle to pressurize the vial and sweeps the
system between samples.
Vent Valve
The Vent Valve allows the loop to ll with sample when it
is in the “O” position and it traps the sample in the loop
when it is in the “On” position.
VERSA HEATED ZONES
The 6-Port Valve
The 6-Port Valve is located inside the valve oven. This valve
has two positions that control the direction of sample and
carrier gas ow through the headspace.
Platen
The Platen is a heater that allows for sample equilbration
at temperatures between 25° C ambient temperature
and 200° C. The Platen has 1 sample equilibrating at any
given time.
Introduction • Page 1-11
This instrument contains heating
elements. Touching any heated
zone during the operation could
cause a burn. The system’s
heaters will activate when
their setpoints are above
ambient temperatures. Keep
all instrument panels fastened
when operating the Versa.

VERSA MECHANISMS
Carousel Drive Assembly
The Carousel Drive Assembly can hold up to 20 vials
and stores the vials in accordance with a predetermined
schedule. The Carousel is capable of rotating to 20
positions allowing a specic vial to be in position for
transport into the heated Platen assembly.
Sample/Elevator Mixer Assembly
The Sample/Elevator Mixer Assembly accomplishes two
functions in the system. It mixes the sample and raises the
sample from the Carousel to the heated Platen assembly
and then from the Platen back to the Carousel when the
sample analysis is complete.
