Polarimeters tackle difficult samples in sugar, chemical and pharmaceutical industries

Xylem’s Bellingham + Stanley brand has added further capabilities to its ADP600 Series polarimeters. 

Not only is the instrument capable of measuring to four decimal places (°A) under Peltier temperature controlled conditions across the UV/Vis spectrum, a new addition, the ADS620P, is now able to measure dark sugar solutions in the near infrared wavelength (880 nm) when used with Celite® clarifying agent. The use of Celite negates the traditional but environmentally unfriendly lead acetate clarification method commonly used in the sugar industry.

Further enhancements benefit those wishing to operate with harsh chemicals such as hydrochloric acid (HCl) used as a solvent within the pharmaceutical industry. HCl is aggressive to stainless steel tubes meaning standard XPC tubes can’t be used. New glass tubes with PEEK endcaps are resistant to such solvents and this combined with a new, optional, Hastelloy® encased temperature sensor makes for corrosion free analysis of samples prepared with such harsh substances.

ADP600 Series instruments are available as multiple, dual or single wavelength models, incorporating XPC technology, Xylem’s patented Peltier temperature control system. The combination of precision optics with fast and reliable onboard temperature control, the ADP600 Series of high accuracy polarimeters are well suited to the demanding applications of regulated environments.

All ADP600 Series polarimeters feature a touchscreen experience that is intuitive, secure and compliant with a range of international standards including FDA regulation 21 CFR Part 11. ADP600 Series instruments are also compliant with pharmacopeia (BP/EP/USP/JP) as well as several other norms including relevant ASTM and AOAC methods.
