Fully Automatic Chemistry Analyzer with Integrated ISE Module

What is the Fully Automatic Chemistry Analyzer with Integrated ISE Module?

This analyzer includes an ion-selective electrode module that measures sodium, potassium, chloride and sometimes calcium from the same sample as the photometric tests. It suits laboratories that need electrolytes with every chemistry panel and want to avoid a separate analyzer.

Overview

The electrode module contains a flow path with ion-selective membranes in contact with an internal reference solution, and a reference electrode that completes the electrochemical circuit. When the diluted or undiluted sample reaches the membrane, a potential difference develops that is proportional to the logarithm of the ion activity. The analyzer converts the potential into concentration using a two-point calibration with standard solutions. Direct measurement uses undiluted whole blood, plasma or serum, while indirect measurement dilutes the sample, and the two modes give slightly different values that must not be mixed within one report. Electrode performance drifts with use, so daily calibration, protein cleaning and periodic electrode replacement are part of normal operation.

How does it work?

A fully automatic analyzer moves tubes from a sample tray or rack to an aspiration station, where a probe with liquid-level and clot detection withdraws a measured volume. Reagent probes add the programmed volumes from refrigerated reagent positions, and the mixture is delivered into a reaction cuvette on a thermostatted rotor held at 37 degrees Celsius. A photometer with interference filters or a diffraction grating reads absorbance at several wavelengths, and the software applies the programmed calculation mode, converts the signal into concentration using the calibration curve and flags results that fall outside the linear range. Automatic dilution and rerun, carryover-free cuvette washing, onboard quality control with Levey-Jennings charts, and reagent inventory tracking are standard. Sample and reagent barcodes, patient demographics and test orders pass between the analyzer and the laboratory information system through HL7 or ASTM interfaces.

What are the key features?

• Ion-selective electrodes for sodium, potassium, chloride and calcium
• Direct and indirect measurement modes with selectable dilution
• Two-point calibration with standard solutions each day
• Electrode status monitoring with lifetime indicators
• Electrolytes reported alongside photometric tests from one sample
• Integrated waste and reference solution handling

What are the technical specifications?

A typical fully automatic chemistry analyzer with integrated ise module configuration offers measured ions of Na+, K+, Cl-, Ca2+ (Ca optional), measuring range Na+ of 90–180 mmol/L, measuring range K+ of 1.0–10.0 mmol/L, calibration of Two-point, automatic, daily and before each run, sample types of Serum, plasma, whole blood, urine and sample volume of 10 µL per ion for direct mode. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Fully Automatic Chemistry Analyzer with Integrated ISE Module is used in routine chemistry panels with electrolytes, dialysis and renal unit monitoring, emergency department electrolyte testing and whole blood electrolyte measurement in critical care. Across the wider Fully Automatic Analyzers class, laboratories also deploy it for hospital routine and emergency chemistry, metabolic, liver, kidney and lipid panels and specific protein measurement by immunoturbidimetry.

Which standards and certifications apply?

Relevant standards and methods include ISO 15189, CLSI EP05, CLSI EP06, CLSI EP07, CLSI C24, IEC 61010-1 and IEC 61010-2-101. Certification candidates for this model are CE, ISO 13485 manufacturing and NMPA class II registration; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

The analyzer needs a stable, level floor or bench with adequate load capacity, a dedicated grounded power supply, controlled temperature and humidity, and purified water of consistent quality. Verify performance at installation with precision, linearity, carryover and method comparison studies following CLSI protocols, and validate the reference intervals against the local population. Daily tasks include checking water quality, reagents and waste, running two or three levels of control and reviewing the calibration status. Weekly and monthly maintenance covers probe cleaning, cuvette washing efficiency and photometer checks, and lamps, tubing and syringes are replaced on schedule. Instruments that handle patient samples must be decontaminated according to the manufacturer procedure before service, and all waste is treated as infectious.

How do I select the right Fully Automatic Chemistry Analyzer with Integrated ISE Module?

Add the ISE module when electrolytes are requested with most chemistry panels, when a separate analyzer would increase sample handling, or when whole blood electrolytes are needed at speed. In the RFQ confirm whether direct or indirect measurement is used, since reference intervals differ, and ask about electrode lifetime, replacement cost and the daily calibration routine.

How does it compare with other Fully Automatic Analyzers variants?

Size the analyzer by daily and peak-hour test volume, then add thirty percent headroom for repeats and quality control. Determine whether you need open reagent channels for cost control or a closed system for convenience. Check the reaction cuvette type, because reusable cuvettes lower consumable cost but require a wash station, while disposable cuvettes simplify maintenance. Confirm the sample volume, which matters for pediatric work, and the reagent capacity per shift. Decide which integrated modules you need, such as ion-selective electrodes for sodium and potassium or immunoturbidimetry for specific proteins. Verify STAT access, first-result time, onboard water consumption and waste handling, LIS interface protocols, and the local availability of service, spare parts and application support before ordering.
