Introducing 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.
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 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.
