Electrolytes and metabolites offer valuable insights into the body's metabolic processes. Electrolyte analyzers measure ion concentrations in the blood, such as potassium, sodium, bicarbonate, chloride, calcium, glucose, lactate, and magnesium. This analysis helps identify medical conditions like kidney failure, heart failure, uncontrolled diabetes, hemorrhage, chemical poisoning, drug overdose, shock, asthma, and chronic obstructive pulmonary disease (COPD). One of the significant long-term advancements in the electrolyte analyzer market is the creation of technologically enhanced devices and the utilization of sophisticated sensors for monitoring critical parameters like pH level and electrolyte concentration. Now, next-generation electrolyte analyzers with advanced features enable increased accuracy and productivity while shortening the turnaround time for each sample, and reducing human input errors.

The CBS series, a direct ISE analyzer, from B&E Biotechnology Co. Ltd. (Yantai, China) measures whole blood or serum samples directly without the need for dilution. The CBS series (e.g., the CBS-5) measures pH, K, Na, Cl, iCa, and TCO2, and offer simple module replacement. These analyzers come with a 20-hole sample tray and can test 60 samples per hour. The CBS series is popular in numerous countries worldwide, with approximately 10,000 units currently installed. Additionally, the company also offers the KS series of indirect ISE analyzers (e.g., the KS 401) which can automatically dilute samples up to 20 times for testing and can process up to 120 samples per hour. They offer easy electrode module replacement and have a long module lifespan (10,000 samples or two months of operation). With capabilities such as switching between serum mode and urine mode with a single click, direct total calcium testing, and a 60-hole sample tray, the KS series is particularly suitable for medium-sized hospitals. Due to its small sample size, flexibility, and ease of use, the KS series is also making waves in the global market.

Both the CBS and KS series of analyzers utilize multi-sensor modules developed from B&E's extensive technical experience in multi-biosensor technology (MBT). The modules, comprising ceramic plates and specific ion-selective membrane ingredients, exhibit impressive linearity, reproducibility, and long-term stability. Leveraging its MBT applications, B&E has also developed an electrolyte biosensor unit (EBU) that can be adapted to automatic biochemistry analyzers for electrolyte analysis to dramatically reduce running costs.
