Fully Automated Chemiluminescence Immunoassay Analyzer

What is the Fully Automated Chemiluminescence Immunoassay Analyzer?

A fully automated chemiluminescence immunoassay analyzer uses magnetic microparticles and acridinium or enzyme-triggered light emission to quantify hormones, tumor markers and infectious disease markers with random access. It is the right choice for hospital and reference laboratories with medium to high test volumes.

Overview

This variant automates sample and reagent pipetting, incubation, magnetic separation washing, substrate or trigger addition and light detection by a photomultiplier tube in a dark chamber. Random-access operation with STAT priority allows any test on any sample in any order. Throughput typically ranges from 100 to 600 tests per hour, with reagent compartments of 20 to 50 positions refrigerated at 2–10 °C. Assay time is 15 to 40 minutes depending on format. Sample volume is 10 to 100 microliters per test, and the dynamic range of several orders of magnitude reduces reruns. Onboard dilution, liquid-level detection, clot detection and reagent inventory tracking reduce hands-on work. Calibration stability of two to four weeks, plus automated quality control management, supports efficient routine workflow.

How does it work?

Immunodiagnostic platforms exploit the specific binding of an antibody to its antigen. In a sandwich assay, a capture antibody on a solid phase such as a magnetic microparticle or microplate binds the analyte, and a labeled detection antibody forms a complex whose signal is proportional to concentration. In competitive assays, labeled and sample antigens compete for limited antibody sites and signal falls as concentration rises. Labels include enzymes such as horseradish peroxidase or alkaline phosphatase, acridinium esters or ruthenium complexes for luminescence, and lanthanide chelates or fluorophores. After incubation and washing to remove unbound label, a photomultiplier, fluorometer or photometer measures the signal, and a calibration curve converts it to concentration. Automation handles pipetting, incubation, washing and result calculation.

What are the key features?

• Random-access operation with STAT priority and continuous loading
• Magnetic microparticle separation with automated wash cycles
• Photomultiplier detection in a light-tight chamber
• Refrigerated onboard reagent compartment with inventory tracking
• Automatic dilution, liquid-level and clot detection
• Bidirectional LIS interface and quality control management software

What are the technical specifications?

A typical fully automated chemiluminescence immunoassay analyzer configuration offers throughput of 100–600 tests/h, sample volume of 10–100 µL, sample positions of 50–200 positions, reagent positions of 20–50 positions, 2–10 °C, assay time of 15–40 min and detector of Photomultiplier tube. 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 Automated Chemiluminescence Immunoassay Analyzer is used in thyroid, fertility and steroid hormones, tumor markers, hepatitis and HIV serology and cardiac markers and bone metabolism. Across the wider Immunodiagnostics class, laboratories also deploy it for infectious disease serology screening, thyroid and reproductive hormone testing and tumor marker monitoring.

Which standards and certifications apply?

Relevant standards and methods include ISO 15189, IEC 61010-2-101, ISO 18113-1, CLSI EP05, CLSI EP07, CLSI EP17, CLSI I/LA23 and ISO 13485. Certification candidates for this model are CE, ISO 13485 quality system and NMPA registration; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place analyzers on a stable bench with temperature and humidity within the stated range, away from direct sunlight, and provide purified water, waste drainage and stable power where required. Follow maintenance schedules for washing systems, probes and optics, and run daily controls at several levels. Verify new lots and calibration according to laboratory procedures, and monitor for interferences such as biotin, heterophilic antibodies or the hook effect. Store reagents at 2–8 °C and observe onboard stability. Handle specimens as potentially infectious, dispose of liquid waste according to biosafety rules, and document maintenance, calibration and operator competence under ISO 15189. Plan service coverage and reagent logistics for the market.

How do I select the right Fully Automated Chemiluminescence Immunoassay Analyzer?

Choose this analyzer for laboratories running over a few hundred immunoassay tests per day across varied menus. State daily tests, menu, STAT share, water supply, reagent policy, LIS protocol and service coverage in the RFQ, and request precision and method comparison data.

How does it compare with other Immunodiagnostics variants?

Match the platform to menu and volume. Chemiluminescence and electrochemiluminescence systems offer wide dynamic range and high sensitivity for hormones, tumor markers and infectious disease serology at medium to high volume. Time-resolved fluorescence suits low-concentration analytes such as newborn screening and fertility hormones. Dry fluorescence readers with cartridges serve small laboratories and emergency testing for cardiac markers. ELISA remains flexible and economical for batch testing and blood screening. Compare reagent menu, closed or open status, onboard reagent stability, sample volume, calibration interval, throughput in tests per hour, and LIS connectivity. Confirm reagent registration in your market, supply reliability and cost per reportable result.
