YSI Life Sciences products provide measurement solutions for clinical, industrial, and research applications. YSI pioneered enzyme electrode technology for whole blood glucose measurements and further developed that technology for many clinical and industrial applications. In addition, instruments using the Clark oxygen electrode and another using a patented opto-fluorescence carbon dioxide sensor are utilized in physiology and bioprocessing applications.
Clinical Research and Diagnostics - YSI analyzers measure glucose in blood, plasma, and serum; and lactate in blood, plasma, and cerebrospinal fluid. The YSI 2300 model is an in vitro diagnostic device. It is used extensively for glucose measurement in diabetes research and glucometer manufacturing settings; and for lactate in exercise physiology and athlete training programs.
Food & Beverage - YSI analyzers measure selected key ingredients and byproducts in process settings and in quality assurance laboratories. Among the analytes are glucose, sucrose, lactose, starch, choline, glutamate and ethanol. In food spoilage applications lactate and ethanol levels provide quantitative evidence of unwanted microbes.
Bioprocessing - YSI analyzers measure important nutrients like glucose, glutamine, and methanol; and can monitor the level of potentially harmful byproducts like lactate, carbon dioxide, and ammonium. Biopharma uses YSI rapid electrode-based measurements to both monitor and control processes.
Biofuels - YSI analyzers measure xylose and glucose to monitor fermentation progress in cellulosic ethanol research and measure residual ethanol during distillation in production facilities.
Physiology Research - YSI analyzers measure key analytes mentioned above as well as dissolved oxygen in cell and subcellular suspensions. Results provide information related to growth factors, metabolism, toxic agents, and more.
