(September 5, 2008) – Spectra Analysis, a leading provider of hyphenated HPLC and GC / FTIR detection, announced today that R&D Magazine has selected the DiscovIR-LC™ for its prestigious 2008 R&D 100 Award. g5~ż���Y���v���ub��a�6�^�E���[^��s���"92$ݹ��A���-q�a�,��G�;/ �݂�N�^j��_x E��"F���ܾ)�������Y���vꍥՑ0)�1. Our current products focus on real-time connection of Infrared Spectroscopy to Gas and Liquid Chromatography. Ignore all but the biggest peaks between 850 and 1500 cm-1 (the “fingerprint region”) unless you are comparing with a spectrum of an authentic sample. High-resolution IR spectra: Note that our example IR spectrum of acetophenone has fairly broad peaks.
