3. INTRODUCTION
The Jerome® J505 Mercury Vapor Analyzer is an ambient air analyzer with a range of 0.05 to 500
micrograms of mercury vapor per cubic meter (µg/m3 Hg). The instrument uses atomic
fluorescence spectroscopy for mercury analysis, which allows the detection cell to be simpler,
smaller, more durable and lighter weight than competing spectroscopy instruments. A smaller
optical cell also requires less flow to purge the system, allowing the J505 to run at a lower flow
rate than competing spectroscopy instruments. A low flow rate is essential for accurate low-level
mercury detection because higher flow reduces the ability to pinpoint the source and dilutes the
sample stream, negatively affecting instrument accuracy.
CAUTION
The J505 is for non-condensing gaseous vapor use only.
DO NOT expose the probe or instrument's intake
to any liquid, dust, or other foreign material.
The J505 is designed for easy operation for quick and accurate analysis of mercury vapor levels.
It has few maintenance requirements. However, please take a moment to read this manual before
operating the instrument. If you have any questions about your application or operation, please
call AZI Customer Service at [phone] or [phone] or e-mail [email protected] for

5. PRINCIPLE OF OPERATION
The J505 uses atomic fluorescence spectroscopy for mercury analysis. As shown below, a
mercury light source is energized to emit light at a 254nm wavelength into a sample cell.
Mercury atoms absorb light with a 254nm wavelength. When a mercury atom in the sample cell
absorbs the light, it is re-emitted at the same wavelength. A photo multiplier tube (PMT) is used
to measure the light emitted at 90° to the source, which correlates to mercury concentration.
During instrument operation, ambient air is drawn through the intake by the pump at a nominal
flow rate of one liter/minute. The sampled air then flows through either a scrubber filter and then
into the sample cell or directly into the sample cell, as controlled by the valve, as shown below.
In the sample cell, the air sample is exposed to light with a 254nm wavelength. Any mercury
present will absorb and then re-emit the light, and the re-emission is measured by the PMT. The
PMT response during scrubbed flow is subtracted from the response during sample flow. The
result correlates to mercury vapor concentration, which is calculated and displayed.
After analysis, the sample air is routed through the exhaust scrubber to absorb any mercury before
the sample stream is discharged.
The instrument is designed and calibrated to elemental mercury vapor only.

6.11. Service Menu
The Service Menu is used to view detailed
battery information, access distributor contact
information or view instrument usage
statistics, as explained in the following
sections.
6.12. Battery Info Screen & Battery Management
The Battery Info screen displays detailed
battery status.
The most important information is the
“Capacity (mA*hr)”. A battery with greater
than 2,700 mA*hr typically provides 10 or
more hours of instrument operation when
autosampling at five-minute intervals. As the
battery ages, the capacity slowly drops.
If the J505 is running on battery power, it will
automatically shut off 90 minutes after last
use, unless the instrument is autosampling.
The “Drain (mA*hr)” and “Capacity (mA*hr)” are used to determine the battery charge level,
which is displayed on the Main Screen as bars (5 maximum) in the battery icon.
The battery capacity is calculated when the battery is fully discharged.
To update the battery capacity once a year:
•Turn on the instrument,
•Fully charge the instrument,
•Disconnect external power,
•Allow the instrument to fully discharge
When fully discharged, the instrument will automatically save the battery capacity and turn off.
Afterwards, charge the instrument and use as normal.
Note: the battery will not charge if the battery temperature is greater than 40 °C.
The battery pack uses NiMH chemistry, which will self-discharge over several months. If the
instrument is not used for a month or longer, plug the instrument in every month to recharge or
leave it plugged in when not in use. Leaving the instrument unplugged for several months will
damage the battery capacity.
