Report on Analysis of Drugs By Infrared Spectrophotometry

Paraffinoma confirmed by infrared spectrophotometry.

Portable Refrigerant Identification by Near Infrared Spectrophotometry

Infrared spectrophotometry of enteric bacteria.

Infrared spectrophotometry is rapidly assuming an important place in the biological sciences. Its value derives from the fact that each organic compound has a characteristic and distinct infrared spectrum that can be used to identify it (Randall et al., 1949). The biologist working with cells or tissues is confronted by a highly complex mixture of substances. The infrared spectrum of a cell, th...

Near-infrared detection of flow injection analysis by acoustooptic tunable filter-based spectrophotometry.

The instrumentation development of a near-infrared (near-IR) spectrophotometer based on an acoustooptic tunable filter (AOTF) and its application as a detector for flow injection analysis (FIA) are reported. In addition to being compact and all solid state, this AOTF-based instrument is very sensitive, has high resolution, and can be rapidly scanned. The latter advantage make it uniquely suited...

Infrared spectrophotometry of M 17 with ISOCAM

We report spectrophotometric observations of the H ii region/neutral medium interface in M 17 obtained with the ISOCAM Circular Variable Filter (CVF) in the spectral range 5.15 to 16.5 m. The lines of singly–ionized species come mainly from the clumpy "neutral" interface, while the H ii region dominates the line emission by higher–ionization species. The emission in the Unidentified Infrared Ba...
