Layered spectroscopic sample element with microporous membrane
First Claim
1. A spectroscopic sample holder comprising:
- a microporous sheet having a top surface, a bottom surface substantially parallel to the top surface, and at least one side surface oriented substantially perpendicular to the top and bottom surfaces, the side surface forming an exposed transit opening configured to contact a material sample and distribute the contacted material sample into the microporous sheet, a first planar support member positioned on, and substantially parallel to, the top surface of the microporous sheet; and
a second planar support member positioned on the bottom surface of the microporous sheet, and oriented substantially parallel to the first planar support member.

Abstract
A spectroscopic sample holder comprises a microporous sheet. The microporous sheet has a top surface, a bottom surface substantially parallel to the top surface, and at least one side surface oriented substantially perpendicular to the top and bottom surfaces. The side surface forms an exposed transit opening configured to contact a material sample and distribute the contacted material sample into the microporous sheet. The spectroscopic sample holder further comprises a first planar support member positioned on, and substantially parallel to, the top surface of the microporous sheet. The spectroscopic sample holder further comprises a second planar support member positioned on the bottom surface of the microporous sheet, and oriented substantially parallel to the first planar support member.
