| The New TE-323 Canister Sampler meets all requirements of EPA Compendium Method TO-14/TO-15. The canister sampler meets EPA protocols for collection of ambient Volatile Organic Compounds VOC . |
Features:
Instruction
on how to operate sampler is on the menu on the front operating
panel
Remote
starting on all 3 sample channels from your site data logger.
Sampler
will operate on 100 to 240v ac 50/60 hz or 12 dc battery,
car lighter, solar panels, UPS
system.
19-inch
rack mount and table top rubber feet.
Condensation
trap.
Flow
rates are 1-300 ml/min.
Individual
stainless steel vacuum and pressure gauges for each canister
port.
Each
channel has its own elapsed timers for the pump and sample
to ensure chain of custody
and Q. C. management of data.
Lights
for each sample channel allows the site operator to see
what is running in a noisy shelter.
PV
has battery back-up and will retain memory and on/off times
for 365 days when sampler
is off or unplugged.
A
three-way valve allows the sampler to purge itself and adjustment
of the flow rate just before
the canister ports. When the sample starts to the canister it takes the flowmeter out of the sample
TE-232-1
instrument shelter for this sampler, with remote sampling,
batter power, solar panel
charging system
Auto
lighter plug for source sampling or emergency response.
Run
two or three cans at once to Q.A. canisters from field site.
Sampler
will fill 6 liter can in 40 min. or less to 10 psi
Sampler
can be ordered with one to three channels
Add
on channels: up to a total of 8 canister channels.
Extra
flow regulations can also be added to allow use of different
run times
There
is no limit on sampling events.
Save
labor with a multi-event sampler.
Proven
dependability in state agencies.

The
front Uniop Operator Panel is a back-lighted panel with four
lines, 20 characters and controls the Siemens PLC. It lets
the operator scroll through the preprogrammed menu to control
the ON and OFF times of pump and canister sampling channels.
It also allows the operator to set the days of the week on
which the sampling will take place and it will keep the total
elapsed time of each channel and pump run. Each channel page
show the site time and the run day of the week.
The
Tisch TE-323 Canister Sampler takes air from the inlet on
the pump and injects it into three (3) separate canisters
at a constant flow rate for a preset time. The excess air
is released through the bypass exhaust. The constant flow
rate and elapsed time allow the operator to compute the
volume of integrated air samples and set the flow using
the built in flowmeter. The flowmeter is only inline and
showing the flow rate when the pump is running and the sample
channels are off. The flowmeter is taken out of the sampling
path when the sample to the canisters is activated. The
samples are pumped through a 12V D.C. pump, which develop
sufficient pressure to control the flow with a regulator.
The pump also samples the air at a flow rate of 5 L/min
which keeps any long inlet sample lines flushed.
A
small, constant flow of sampled air is pumped into the sample
canisters. You can set the sampler to turn on the pump for
any purge time before the sample time is turned on. Following
sampling, the pump is turned off, the sample channel solenoid
valve is turned off and a check valve seals the canister
until an operator can close the canister valve. The water
trap on the front panel keeps excessive water out of the
sampling path. All tubing inside sampler is Chromatograph-grade
stainless steel. A 47mm inlet particulate filter is attached
to the pump inlet on the back of the sampler. A Teflon-impregnated
glass-fiber filter is used inside the filter holder to trap
particulates. All gauges are stainless steel and are leak-free
and nonbiasing. |
