- Canister Samplers
-
ATEC manufactures single and multi-port
embedded computer controlled canister samplers.
These instruments are routinely used for collecting VOC samples.
-
- Cartridge Samplers
-
ATEC produces single and multi-port
embedded computer controlled cartridge samplers. These
instruments are typically used for collecting carbonyl samples.
-
- Hexavalent Chromium (Cr6)
Filter Samplers
-
ATEC has recently introduced a multi-port embedded
computer controlled hexavelent chromium (Cr6) filter sampler. This
sampler is ideally suited for use in the US EPA National Air Toxic Trends
Stations program (NATTS).
ATEC produces several automated
samplers that combine canister, cartridge, and/or hexavalent chromium
(Cr6) filter sampling in one instrument.
- Custom Samplers
-
ATEC has designed and manufactured a variety of custom samplers for unique sampling
needs of many clients.
A more extensive overview of ATEC products can be seen
below.
ATEC TOXIC
AIR SAMPLERS
ATEC manufactures several
models of cartridge samplers for carbonyl sampling, canister samplers for
VOC sampling, and combined cartridge, canister, and
hexavalent chromium (Cr6) filter samplers for complete
toxic sampling using one instrument. The following is a summary of ATECs
line of toxic air samplers.
Cartridge Samplers for
Carbonyl Sampling
Model 8000a multi-port
sampler with an internal PC with touch screen display. The computer
provides easy to use automated function keys to provide flexible scheduling,
leak checking capability, and data retrieval. A unique SOP screen guides
the operator through set-up, leak check, and scheduling a sampling time.
The Model 8000 offers a number of data quality assurance features along with
monitoring sampling status and error conditions. The Model 8000 can be
expanded with up to 2 additional independent channels and 16 additional
ports. An optional label printer is available to print labels containing
important sampling information.
Model 2200-1C A single
port cartridge sampler with all of the features of the Model 8000.
Model 2200-2C A carbonyl
sampler designed to acquire two samples over a specified time period. This
instrument is generally used to obtain a co-located sample along with a
scheduled primary sample. Both channels are completely independent and can
run at different times. The Model 2200-2C uses an internal PC with
touch screen display and has all of the automated features of the Model
8000.
Canister Samplers for
VOC Sampling
All ATEC canister samplers
can be configured for standard sub-ambient sampling or optional pressurized
sampling.
Model 2200-1 A canister
sampler designed to obtain an accurate VOC sample over a specified time
period. The Model 2200-2C uses an internal PC with touch screen display and
has similar automated features found in the Model 8000. The instrument
contains a precision pressure transducer to monitor the can pressure as a
function of time to ensure uniform filling. The menu driven software allows
easy sampler set-up, leak check, and data and status retrieval.
Model 2200-12 This sampler
is identical to Model 2200-01 except it is a two port sampler with a single
mass flow controller. Two samples can be collected at different times over
a designated sample period.
Model 2200-22 This sampler
is identical to the Model 2200-01 except it contains two independent
channels to obtain VOC samples concurrently or at different times.
Model 8001 An 8-port
sampler using an internal PC with a touch screen display. The unit contains
one mass flow controller that can fill eight canisters during different
sampling periods.
Model 8001-16 A 16-port
sampler using an internal PC with a touch screen display. The unit contains
one mass flow controller that can fill sixteen canisters during different
sampling periods.
Toxic Air Samplers for
Combined Carbonyl, VOC, and/or Hexavalent Chromium (Cr6) Sampling
Model 2200 This sampler
contains a single channel cartridge port for carbonyl sampling as well as a
single channel canister port for VOC sampling. The instrument is controlled
by an internal PC with a color tough screen display. Sampling periods are
easily programmed for both the cartridge and the canister using one
scheduling screen on the front panel display. The unit also has a special
SOP (Standard Operating Procedure) screen that ensures that the operator
correctly installs, leak checks, and schedules the sampler correctly. The
Model 2200 can also be ordered with an optional canister pressurizing system
to increase the size of the canister sample. This
model can be upgraded to sample hexavalent chromium (Cr6).
Model 2200-2 This sampler
has all of the features of the Model 2200, but contains two independent
canister and two independent cartridge channels for co-located sampling.
Model
3400 This instrument has all the features of the
Model 2200, but can sample up to four channels of any combination of
canisters, cartridges, or filters. This sampler is ideally suited for
use in the US EPA NATTS program since it can simultaneously sample one
canister, one carbonyl DNPH cartridge, and two hexavalent chromium (Cr6)
filter samples.
