The sample enters the Thermo Scientific Orion 2117HL chloride analyzer
and passes through the inlet valve, bypass/needle valve, inlet filter, pressure
regulator, flow meter and into the restrictor tubing. The sample then passes
through the flow cell manifold into the flow cell as air is introduced from
the air pump to ensure proper mixing and fast response. The sample passes
the chloride sensing electrode, reference electrode and ATC probe and then
flows into an atmospheric drain via the diverter valve.

Thermo Scientific Orion 2117HL High Level Chloride Analyzer User Guide
The sensing electrode responds logarithmically to changes in the chloride
ion concentration. This response is described by the Nernst equation:
E = Eo+ 2.3 (RT/nF) log (C/Ciso)
Where:
E = measured electrode potential, mV
Eo= potential, when C equals Ciso, mV
R = ideal gas constant
T = temperature of sample, degrees K
n = valence of ionic species (-1 for chloride ion)
F = Faraday’s constant
C = effective chloride ion concentration (activity)
Ciso = concentration (activity) of chloride ion where potential E is
temperature independent (isopotential point)
The above equation indicates that the measured potential varies with both
temperature and the concentration of the ion of the interest. In order to
eliminate error caused by fluctuations in sample temperature, the 2117HL
microprocessor constantly updates temperature corrections from data
supplied by the ATC probe.
From the Nernst equation, the theoretical response of a chloride ion
selective electrode to a ten-fold change in concentration at 25 °C is
-59.16 mV. This is referred to as the electrode slope (S). Most electrodes,
however, do not exhibit a theoretical slope. Therefore, the analyzer is
calibrated to determine its actual value. Two standards are used to provide
information necessary for the microprocessor to compute the actual slope
and E0for use during sample analysis.

Principles of
Calibration
Calibration procedures for analytical instruments are important and must
be performed carefully. The calibration procedure used in the Thermo
Scientific Orion 2117HL analyzer is a variation of Double Known
Addition (DKA) using advanced electrode and flow cell technology. This
method has the distinct advantages of being fast, easy and accurate.
Before calibration begins, the diverter valve is pushed in to divert flow from
the measure drain, allowing the flow cell to fill.
At the beginning of the DKA calibration the actual concentration in the
sample is unknown. The analyzer measures the potential (Es) and stores
this value in the microprocessor. A known amount of standard 1 solution
is added to the flow cell, which increases the concentration (Cs) with a
corresponding known amount (dC1). During this process, air is pumped
into the flow cell, thoroughly mixing sample and standard in a closed-
loop system. The new potential (E1) is measured and stored automatically
when stability is reached. Adding standard 2, preferably 10 times more
concentrated than standard 1, increases the concentration (dC2) in the
sample reservoir. Again, the new potential (E2) is measured and stored
when the reading is stable. Now, we have the following three unknowns:
Es=Eo+ S(Ts/298.15) log (Cs/Ciso)
E1=Eo+ S(T1/298.15) log [(Cs+ dC1)/Ciso]
E2=Eo+ S(T2/298.15) log [(Cs+ dC1+ dC2)/Ciso]
S is the Slope at 25 °C (298.15 K)
T is the temperature in Kelvin, measured when the potential E is measured.
Es, E1, E2have been determined during the calibration procedure. The
microprocessor solves these three equations, to obtain the values of S
and Eo. The calibration result is stored for use during online monitoring
to convert the measured potential and temperature in the sample into
concentration values in either ppm or ppb.
When the calibration is complete the flow cell drains as the sample flow
returns. The flow cell volume returns to the measurement level. After
allowing approximately 30 minutes for concentrated calibration solution
to be flushed from the system, the 2117HL analyzer can begin sample
measurement again.
In addition to Double Known Addition (DKA), the 2117HL analyzer also
allows the operator the ability to perform an offline calibration.

The offline calibration feature of the 2117HL analyzer allows the operator
to adjust the analyzer to values determined by alternate methods used in
their laboratory such as elemental spectroscopy and ion chromatography.
The offline calibration is essentially a one point calibration. To perform
an offline calibration a sample is taken from the bypass of the analyzer, the
sample concentration value is stored in memory, the sample is analyzed
by an alternate method of choice, the previously stored reading is adjusted
to the lab method result and the analyzer is then returned to the analysis
mode. The term “offline calibration” refers only to the fact that a sample
from 2117HL analyzer bypass is taken “offline” for laboratory analysis; in
fact, no downtime is experienced during the procedure and the analyzer
remains online throughout.
