Microsampler and method of making the same
| DWPI Title: Micro-sampler for hermetically sealing sample, has heating element fixed in proximity to change material, and for unblocking seat opening upon activating valve, and normally-opened valve located between chamber and normally-closed valve |
| Abstract: An aspect of the present disclosure relates to a microsampler for hermetically sealing a sample. In particular, such microsamplers can be useful for encapsulation of chemical, biological, and explosive samples for the purposes of archival sample storage. Methods of making and using such microsamplers are also described herein. |
| Use: Micro-sampler for hermetically sealing a sample such as chemical, biological, and explosive samples. |
| Advantage: The micro-sampler provides a thin aluminum holder to allow efficient heat removal from micro-sampler walls, while providing a ready unit for the micro-sampler installation and replacement after use when a Peltier cooling unit is particularly beneficial due to lack of moving parts to improve high reliability, so that relatively small footprint and weight per unit of heat energy can be removed. |
| Novelty: The micro-sampler has a chamber with an inlet (102), where the chamber (101) is a under vacuum. A normally-opened (NO) valve (120)comprises a valve orifice (125) in fluidic communication with the inlet to activating the NO valve, a first phase-change material (105) located in proximity to the valve orifice, and a first heating element (106) fixed in proximity to the first phase-change material. A valve seat is fixed above the NO valve, and comprises a seat opening (135). A normally-closed (NC) valve (110) is fixed on the valve seat, and comprises a second phase-change material to block the first seat opening to activating the NC valve. A second heating element is fixed in proximity to the second phase-change material, and unblocks the first seat opening upon activating the NC valve. The NO valve is located between the chamber and the NC valve. |
