New Enhancements Enable Polarimeter to Tackle Difficult Samples

Bellingham + Stanley, a Xylem brand, has added further capabilities to its premier polarimeter, the ADP600 Series, since its launch last year.

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 today. Additionally, the instrument now displays ;POL; alongside the measured sugar degrees (°Z) and calculated purity value.

Further enhancements benefit those wishing to operate with harsh chemicals such as hydrochloric acid (HCl) used as a base chemical or as a solvent within the pharmaceutical industry. HCl is aggressive to stainless steel tubes so measuring with standard XPC tubes becomes a problem. New glass tubes with PEEK endcaps are resistant to such chemical compounds 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 of polarimeters are available as multiple, dual or single wavelength models, with readability of optical rotation to 4 decimal places. Now with 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 multiple wavelength, high accuracy polarimeters are well suited to the demanding applications of regulated environments.

All ADP600 Series polarimeters feature latest firmware, meaning your touchscreen experience is not only intuitive but is also 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.
