  • Separating materials for linking TLC and FTIR
    Patent number: 5882939
    Abstract: The invention concerns separating materials for thin-layer chromatography, the materials having a sorbent layer formed from sorbent particles and disposed on a carrier. A reflection intensifier, preferably magnesium tungstate and/or Bi.sub.2 O.sub.3, is added to the sorbent layer. This addition comprises at least 10 wt % relative to the amount of sorbent. In preferred embodiments, the particle size of the reflection intensifier is 3 to 5 .mu.m and the amount of the reflection intensifier is 0.6 to 15 times the amount of sorbent. These separating materials are particularly suitable for the in-situ measurement of FTIR spectra. The invention also concerns the use of these separating materials for the in-situ measurement of FTIR spectra.
