Fully Automatic Chemistry Analyzer with Immunoturbidimetry Module

What is the Fully Automatic Chemistry Analyzer with Immunoturbidimetry Module?

This analyzer integrates immunoturbidimetric detection for specific proteins such as CRP, immunoglobulins and transferrin, so that protein assays run alongside routine chemistry. It suits laboratories consolidating immunoassay work onto a chemistry platform.

Overview

Immunoturbidimetry measures the light scattered or absorbed by antigen-antibody complexes that form when reagent antibody is added to the sample. The increase in turbidity is proportional to analyte concentration over a defined range and is read at a wavelength such as 340 or 550 nanometers. The analyzer schedules these assays with an initial sample blank and often with an antigen-excess check, because very high concentrations can cause a paradoxical fall in signal. Reaction times are longer than for simple colorimetric tests, typically five to ten minutes, which affects effective throughput. Antibody reagents must be stored refrigerated and used within their stability period, and calibration curves are run with multi-point calibrators. Common analytes include CRP, immunoglobulins A, G and M, transferrin, apolipoproteins, rheumatoid factor and HbA1c.

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?

• Turbidimetric reading of antigen-antibody complexes at dedicated wavelengths
• Sample blank for each measurement to correct sample turbidity
• Antigen excess check for high-concentration samples
• Multi-point calibration with refrigerated antibody reagents
• Longer reaction windows for latex-enhanced assays
• Combined report with routine chemistry from the same sample

What are the technical specifications?

A typical fully automatic chemistry analyzer with immunoturbidimetry module configuration offers measurement principle of Immunoturbidimetry with latex enhancement, wavelengths of 340 nm and 550–600 nm selectable, reaction time of 5–10 min per assay, CRP measuring range of 0.5–300 mg/L with dilution, calibration of Multi-point, 5 to 6 levels, lot-specific and antibody reagent storage of 2–8 °C refrigerated onboard. 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 Immunoturbidimetry Module is used in inflammation monitoring with CRP, immunoglobulin measurement in immunology, nutritional and apolipoprotein testing and diabetes monitoring with HbA1c. 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 Immunoturbidimetry Module?

Add immunoturbidimetry when specific proteins are requested frequently and consolidating them reduces sample handling and cost. In the RFQ confirm which analytes the module supports with validated parameters, the calibration frequency needed, and how the analyzer handles antigen excess. Note that reaction time reduces effective throughput, so plan capacity accordingly.

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.
