Spectrophotometers were originally developed for the absorption measurement of liquid samples. In recent years, however, high-precision, high-energy spectrophotometers have hit the market due to the rapid increase in reflection and absorption measurements on solid samples, including semiconductors, films, glass, and absorbing materials. In the meantime, the field of life sciences demands high-throughput analyzers offering high-sensitivity and high-speed measurement of ultra-trace samples. The fields of pharmaceuticals and drug manufacture demand security, audit-trail and other GXP- and FDA 21 CFR Part 11-compatibility functions. Therefore, the spectrophotometer software must also support these functions. Shimadzu develops hardware and software to meet all these requirements.
