Tedlar bags are a popular medium for collecting air samples because they are light, portable, and inexpensive. However, Tedlar bags are semi-permeable and samples must be tested shortly after collection to maintain the integrity of the sample. This time range is usually between 24 and 72 hours, depending on the analyte of interest and method compliance. Automated samplers help laboratories meet the required fast turnaround and eliminate differences in operator sampling, thereby improving reproducibility.

Detail
The Wasson-ECE Tedlar bag automatic sampler is designed to help busy laboratories by increasing throughput and reducing manpower requirements. Automatic sampler can hold up to 16 sample bags. An onboard diaphragm vacuum pump pumps the sample from the Tedlar bag to the gas injection valve on the Agilent Gas Chromatograph (GC) for analysis. Sampling is controlled by GC software sequence editor; No additional software is required.
