Automatic Biochemistry Analyzers: Principles, Applications, Brands, and Buying Guide

Automatic biochemistry analyzers are highly advanced instruments with a wide range of applications in our daily lives, particularly in medical settings and vital sign detection. They play a crucial role in disaster relief and healthcare. But what exactly are these instruments and how do they work? Additionally, which well-known brands are available, and how can one make an informed choice? In this article, we'll comprehensively explore these aspects.

Understanding Automatic Biochemistry Analyzers

An automatic biochemistry analyzer is a sophisticated instrument that employs photometric colorimetry to measure specific chemical components in bodily fluids. Its primary purpose is to provide clinical tests covering biochemical, hematological, immunological aspects, and more for various levels of medical facilities. These tests aid in disease diagnosis, treatment, prognosis, understanding health status, and more. Hospitals commonly use automatic biochemistry analyzers for routine check-ups, disease screening, and confirmation tests. These analyzers offer quick measurements, high accuracy, and minimal reagent usage.

Operating Principles of Automatic Biochemistry Analyzers

Automatic biochemistry analyzers automate sampling, mixing, incubation, detection, result calculation, and cleaning processes, either partially or entirely. These devices rely on absorption spectroscopy, a fundamental principle in spectral technology. This principle holds true whether using the fastest modular automatic biochemistry analyzer or the original photometric colorimeter designed for manual colorimetry.

Applications of Automatic Biochemistry Analyzers

Due to their numerous advantages, automatic biochemistry analyzers find applications in various domains. Their key applications include family planning services, testing at epidemic prevention stations, and usage in medical facilities of different sizes. The efficiency of these analyzers significantly reduces the workload and improves productivity in these settings.

Measurement Requirements for Automatic Biochemistry Analyzers

• Samples: Serum, urine, cerebrospinal fluid, etc.
• Reagents: Single or double reagents
• Dual Wavelength: Utilizes a main and a subsidiary wavelength to eliminate interference during detection.
• Calibration Standards: Used to compare unknown sample concentrations.
• Quality Control Samples: Monitor instrument and reagent status during daily operations.

Detection Methods for Automatic Biochemistry Analyzers

1. Endpoint Method: Calculates concentration based on absorbance at the reaction endpoint, commonly used except for specific items like enzymes, BUN, and CRE.

• Single-point Endpoint Method: Uses absorbance at the reaction endpoint for calculation.
• Two-point Endpoint Method: Involves measuring absorbance before and at the reaction endpoint to ensure result accuracy, especially for double-reagent use.

2. Fixed-time Method: Calculates results by measuring the difference in absorbance between two points during an ongoing reaction. Useful for detecting nonspecific items like creatinine.

3. Continuous Monitoring Method: Utilizes the change in absorbance values over time to calculate results, especially for enzyme activity or enzyme metabolic products.

Selecting the Right Automatic Biochemistry Analyzer

When choosing an automatic biochemistry analyzer for a medical facility, consider the following factors: model applicability, cost-effectiveness, reagent accessibility, regional differences, and after-sales technical support. Choose a model slightly larger than your current workload requirement to accommodate future growth, considering both economic factors and ensuring the instrument remains relevant throughout its lifecycle.

Regional differences and after-sales support vary, so consider local sales status, existing similar machines, and the reputation of sales and manufacturing companies. For larger cities with concentrated sales and agents, prioritize cost-effective instruments, while smaller cities and town medical units should focus on modular, independently usable instruments for uninterrupted operations even in case of module failure.
