1、 Technical principles and core modules

Optoelectronic Colorimetry and Spectroscopy Technology

Based on the Lambert Beer law, the concentration of a substance is calculated by measuring the absorbance of specific wavelengths of light.

Optical system upgrade:

Pre splitting and post splitting: The new equipment adopts post splitting technology, combined with a lens group to focus the beam onto a small colorimetric cup, reducing reagent consumption by 40% -60%.

Grating splitting: Decompose light into more than 10 wavelengths, eliminate electromagnetic interference through optical/digital signal conversion technology, and improve testing accuracy by nearly 100 times.

Closed optical path: no maintenance required, accurate light distribution and long service life.

thermostatic system

Constant temperature liquid circulation indirect heating: The colorimetric cup is filled with odorless and non evaporating stable constant temperature liquid, with temperature fluctuations of ≤± 0.1 ℃, overcoming the defects of water bath pollution and uneven air bath.

Temperature control range: 37 ℃± 0.3 ℃, meeting the stringent temperature requirements for biochemical reactions.

Sample processing module

Intelligent probe technology:

The liquid level sensor prevents probe damage and the blood clot alarm function reduces sampling errors.

Up and down anti-collision design, to avoid probe damage caused by misoperation.

Multiple sets of stirring rods:

Imitating the manual cleaning process, the first group is stirred while the second group is cleaned synchronously, and the third group is rinsed with warm water and air dried to reduce cross contamination.

Spiral high-speed rotating stirring enhances strength and avoids microbubble interference.

Reagent system

Open reagent support: Hospitals can independently choose reagent suppliers to balance price and quality.

Reagent refrigeration function: Store at a low temperature of 2 ℃ -10 ℃ to prevent reagent failure.

Barcode recognition: automatically checks the type, batch number, expiration date, and calibration curve of reagents, supporting high-speed detection needs.

2、 Key performance indicators

Accuracy and stability

Absorption error: The allowable error is ± 0.025 at 0.5 absorbance and ± 0.07 at 1.0 absorbance.

Repeatability: Coefficient of variation (CV) ≤ 1.5% to ensure the reliability of the results.

Carrying contamination rate: ≤ 0.5%, to avoid cross interference between samples.

detection efficiency

Speed range: 300-1200 tests per hour (e.g. Hitachi 7170S with ISE unit can reach 1200 tests per hour).

Automatic retesting function: Large equipment can detect over 1000 times per hour, meeting the high load requirements of clinical practice.

Project scalability

Electrolyte detection: The optional ISE module can detect potassium, sodium, and chloride ions, saving department costs.

Immunoturbidimetric function: Analyze indicators such as immunoglobulin and complement C3/C4 to assist in the diagnosis of autoimmune diseases.
