MicroValve Canisters (Patent Pending)

Micro-QT and Micro-QT2 Valve Canisters are the next generation in canister sampling devices. Micro-QT, or “Quarter-Inch Tube” Valves, have several advantages over other canister valves. Micro-QT/QT2 valves minimize the volume of outside“contaminated” air that is introduced into a canister when testing vacuum or otherwise making a connection to a sampling line or GC inlet. The inclusion volume for the Micro-QT Valve is 0.01cc, which is ten times smaller than other miniature quick connect ttings. e inclusion volume is the “outside” volume that is introduced into a “system” when male/female valve connections are made. When testing vacuum through a Nupro Valve, approx. 2cc of air is introduced into a canister, which is the combined volume of the Nupro Valve and an external gauge. is is 200 times more air than using a pre-evacuated test gauge with Micro-QT valve ttings.

The internal Silonite coated sealing spring in a MicroValve is stronger than those used in Swagelok Miniature Quick Connects,to further reduce the potential for leaks even at cold storage temperatures (-15°C). A compression tting cap is also available, which when used with the MicroValve creates a lower combined leak rate than any other currently accepted canister valve.

Micro-QT and Micro-QT2 valves are referred to simply as MicroValves when describing features common to both.
Micro-QT/QT2 valves are recommended for canister sizes under 3L – where lower ow rates during canister cleaning are not an issue.

	Micro-QT Valve The Micro-QT Valve is designed exclusively for “through the valve” sampling . This valve is optimized for volatile or even light semivolatile compounds when performing rapid sampling. Like the Micro-QT2 Valve below, the Micro-QT Valve is compatible with all existing Entech sampling devices by simply adding a female QT to 1/4” adapter (PN 30-22800). New sampling canisters optimized for MicroValves are shown on pages 66–67.
	Micro-QT2 Valve The Micro-QT2 Valve is a two-piece valve that can be removed in the eld to draw in a sample “around the valve” without requiring a separate sampling device. is allows recovery of the heavier semivolatile compounds that might otherwise condense in the valve on the way into the canister. The ability to sample around the valve is unique to the Micro-QT2 valve design. This valve can also be sampled“through the valve” using a Restricted or Time Integrated Sampler.
	HDS Micro-QT2 Valve The HDS Micro-QT2 Valve is a two-piece valve that can be removed in the field to perform time integrated sampling from hours to weeks without requiring a separate sampling device. Learn more about HDS on pages 70–71.
