UV Absorbance Analyzer

The DCP007 Series is an advanced dual wavelength photometer designed to accurately measure absorbance in the UV region of the electromagnetic spectrum. Optical fibers are utilized to transmit light from a source within the DCP007 instrument through an in-line sample cell and back again to a sensitive detection system to calculate the concentration of many substances in real time. The absence of electrical power in the light transmission system allows sample cells to be fitted in hazardous areas without any concern for electrical certification and approval. The DCP007 is an excellent and cost effective solution for measuring flow stream absorbance and concentration in a process environment in place of far more expensive scanning type analyzers.

DPC007 UV instruments are supplied tuned for specific applications. They use solid state light sources and do not suffer from the zero drift and signal noise problems seen on traditional systems where mercury vapor lamps are utilized. Measurement is independent of pressure, temperature, density and viscosity. The DCP007 has no moving parts, so maintenance costs are exceptionally low while repeatability and reliability of measurement are assured by high quality fiber optic cables and stable, long lasting light sources.

In line calibration and QA is made possible using an innovative insertable cuvette method. Standard cuvettes containing materials of known and verifiable absorbance are placed in the light path to allow performance checking and calibration of the inline measurement. Cuvettes provide a direct correlation to offline measurement in a spectrophotometer for added confidence in measurement.

The DPC007 is ideal for chromatography and filtration separation systems where accurate, reliable and noise free concentration measurement is vital for optimum yield performance. In-line flow cells are durable and available in sizes from ½” to 4” as standard. Other/custom line sizes are available upon request.

DPC007 in-line process analyzers can meet your application requirements accurately, repeatably and reliably at a low cost with low continuing maintenance.
