Thumbnail Filmstrip of TE-1002-4 Module Plug Coupler for Dual Sampling Module Images
The TE-1002-4 Module Plug Coupler is a precision-machined replacement component for Tisch Environmental's TE-1002 dual sampling module system. This critical connector component ensures secure coupling between the upper and lower chambers of the dual sampling module, maintaining leak-proof operation during PUF (polyurethane foam) air sampling applications.
Technical Function
The module plug coupler serves as the interface connection point in the dual-chamber aluminum sampling module that houses both the particulate filter system in the upper chamber and the PUF vapor collection cartridge in the lower chamber. This component works in conjunction with gaskets to provide a leak-proof seal during the sampling process, ensuring accurate sample collection and preventing cross-contamination between the particulate and vapor collection stages.
Compatibility
The TE-1002-4 Module Plug Coupler is specifically designed for use with:
- TE-1002 Dual Sampling Module
- TE-1002 Particulate Vapor Sampling Module
- PUF high volume air samplers that collect airborne particulate and vapor contaminants, typically used for volatile organic compounds and airborne pesticides
This coupler works with other TE-1002 system components including the TE-1002-3 Module Body, TE-1002-2 Module Reducer, TE-1002-6 Upper Module Gasket, and TE-1002-8 Lower Module Gasket.
Applications
The TE-1002 dual sampling system incorporating this plug coupler is designed to meet the requirements described for sampling using US EPA methods TO-4A, TO-9A, and TO-13A. Applications include determining common pesticides & polychlorinated biphenyls (PCBs) per TO-4A, determining polyhalogenated dibenzo-p-dioxins & dibenzofurans (PHDDs/PHDFs) per TO-9A, and determining common polycyclic aromatic hydrocarbons (PAHs) per TO-13A.
Maintenance Notes
Regular inspection of the module plug coupler is recommended during routine maintenance to ensure proper sealing integrity. The threaded lower canister design allows for removal with the cartridge intact for immediate exchange, making coupler inspection and replacement straightforward. When replacing this component, ensure proper alignment with mating surfaces and verify gasket condition for optimal performance.
