Editor: Dipl.-Chem. Marc Platthaus

By detecting ultraviolet and visible light passed through or reflected by samples, UV-Vis spectrophotometers are used mainly to identify and quantify unknown substances.

This type of instrument is increasingly popular, and demand for UV-Vis spectrophotometers continues to expand, even in newly emerging economies. They are applied for research and development and quality control in a wide range of fields. Accordingly, when users select an instrument like a UV-Vis spectrophotometer, they focus on topics like cost effectiveness, operability, compliance with various national regulations and enhanced management functions.

Addressing these needs Shimadzu introduces the new UV-1900 UV-Vis Spectrophotometer. It is equipped with an ultrafast scan function that enables data acquisition of 29,000 nm/min. It takes about three seconds to measure in visible region. By performing repeat measurements, the process of sample changes in chemical reactions can be analyzed in a short time.

The instrument achieves a resolution of 1 nm and can perform analyses compliant with the pharmacopeia of various countries, including FDA 21 CFR Part 11.

The UV-1900 features a large, easy-to-use color touch panel as well as excellent operability. The touch panel is deployed at the ideal viewing angle based on ergonomics. It can also be operated using the stylus pen provided, which can be stored in the unit. Target analyses can be performed with ease due to the intuitive operation. All functions are directly reachable with large and easy to understand icons. In addition, UV-1900 patented diffraction grating technology ensures low stray light with high resolution and one of the largest ranges of linearity.

While UV-1900 can be operated as a standalone instrument the new Labsolutions UV-Vis (Shimadzu's UV-Vis control software released simultaneously) expands user possibilities. This software also contributes to data pass/fail judgments via its spectral evaluation functions.

It provides fully integrated data management with other analysis instruments as requested by the different guidelines and regulations relating to electronic records and electronic signatures. Data transfer to spreadsheet software and batch text export of multiple data sets are easy, thereby improving work efficiency.
