  • Excellent Sampling System Hygiene

Now featuring all new low flow stability for extremely precise Time Weighted Average Sampling

Low Level TO-15 monitoring requires consistent analyte recovery while collecting the maximum sample volume possible to support larger preconcentration volumes or repeat analyses from the same canister. The CS1200E will reliably fill canisters at a constant rate with better demonstrated recovery of TO-15 compounds than any other sampler.

An important component for Low Level TO-15

Untreated 300 series stainless steel is 67–70% iron, which is very reactive toward many TO-15 compounds. In addition, untreated stainless tubing has an internal oxide layer that readily adsorbs polar and heavier VOCs. The standard CS1200E inlet now comes internally polished, passivated, and Silonite®coated to insure maximum recovery of all target compounds – virtually eliminating losses and carryover. A Silonite® coated filter is placed on the inlet to completely eliminate dust and particulate intrusion during sampling. The rain guard is capped to avoid contamination during shipping.

CS1200E Flow Controller Features

Time Weighted Average Sampling

Accurately fill 6L Silonite® Canisters with integration times from 1 hour to 1 week with demonstrated recovery of TO-14 / TO-15 compounds.

McDaniels Controls, Inc. Gauge

Our exclusive gauge with a leak-tight ¼” compression fitting avoids any need for absorptive Teflon® tape in the controller flow path.

Silonite® Coated Inlet Lines

Inlet lines are electropolished, then Silonite® coated. (Optional Silonite® coating of complete sampler is also available).

Amazing Low Flow Stability

More stable and reliable flow rates than any other controller.

Silonite® Coated Filter

A large Silonite® coated stainless steel filter is positioned at the inlet to maintain an inert and unobstructed flow path by eliminating particles.

Excellent Sampling System Hygiene

The CS1200E can be easily capped off during shipping to prevent any risk of sampler contamination.

Flow Professor Calibration System

Flow ProfessorIntroducing the all-new FlowProfessor™, the easiest and most accurate way to calibrate your Entech CS1200E field samplers. Using the latest CS1200E technology updated in 2014, the Flow Professor totally automates the calibration process for sampling into canisters as small as 450cc and as large as 15L. Just set the canister size, the sampling duration, and the vacuum to leave in the canister after sampling (typically 2” Hg) from the simple Windows® menu, attach the Flow Professor to the CS1200E, and select START CALIBRATION. The FlowProfessor™ automatically adjusts the flow setting of the CS1200E to obtain the correct flow every time. The sophisticated software even adjusts for estimated field temperatures and sampling site elevation to optimize sampling rates under any environmental condition. Trying to accomplish those calculations manually can be dicult at best.

Using the new CS1200E with greater low-flow stability, accurate filling of a 6L canister can be set from 1 hour to a full 2 weeks. Can you imagine doing continuous monitoring at a field location and only collecting 2 samples a month? Now that’s all easily automated with the FlowProfessor™ from Entech. Even the quality of the restrictor and diaphragm are verified to ensure consistent flow rates in the field. Generate a calibration report for long-term documentation, and then send the CS1200E out to the field in Entech’s new shipping boxes that perfectly protect both the canister and the flow controller in a single, compact container.

The FlowProfessor™ + CS1200E + Silonite® Sampling Canister + You. A winning combination for today’s air monitoring lab.

Industrial Hygiene Sampling

Canisters and Bottle-Vac™ samplers provide an exciting new way to collect whole air samples in the workplace to determine exposure levels. Whole air sampling does not attempt to “extract” chemicals at the time of sampling, and is therefore inherently more reproducible and defensible than badge, cartridge, and tube sampling. Whether performing Ceiling, STEL, or Time Weighted Average sampling, detection limits are always the same because the total amount of sample collected in each case is the same. Interaction of the target compounds with the matrix is substantially reduced by leaving the sample analytes in the gas phase, virtually eliminating any matrix effects on target compound measurements.

Ceiling Measurements with Canisters

Ceiling measurements have historically been a challenge because there is no way to quickly and reproducibly collect a sample using tube and badge samplers. MiniCans™ and Bottle-Vac™ samplers make this easy. Simply opening and closing the evacuated container accomplishes the task in just a few seconds with extremely high precision. These whole air samplers can easily be checked prior to filling to show that they are still under vacuum; assuring a defensible sample collection process. Detection limits are equal whether performing STEL or TWA sampling procedures, because the sampling container is always filled with the same amount of sample. Even a small 50cc MiniCan™ or Personal Monitor using vacuum to collect the sample will achieve the same detection limits as the larger sampling MiniCans™ and Bottle-Vacs™ because just 0.25cc is typically used during each analysis to achieve a 0.05 PPM detection limit for most compounds by GC/FID or GCMS.process.
