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 |
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. |
