Introduction

GB/T 44147-2024 Standard Interpretation and Application

1. Background and Significance of Standard Formulation

Liquid chromatography coupled with atomic fluorescence spectrometry (LC-AFS) is an important analytical testing instrument, widely used in environmental monitoring, food safety, medical testing and other fields. The formulation of GB/T 44147-2024 fills the gap in the performance test methods of such instruments in China and provides a technical basis for standardized testing in related industries.

2. Comparative analysis of standard frameworks

Standard dimensions	GB/T 44147-2024	Comparison standards	Technical advantages
Test scope	Liquid chromatography and atomic fluorescence spectrometry	Only liquid chromatography or atomic fluorescence spectrometry	Covering combined technologies, more comprehensive
Performance indicators	Baseline drift, minimum detection amount, repeatability and long-term stability, etc.	Single or incomplete indicators	More comprehensive test dimensions
Applicable scenarios	Environmental monitoring, food safety, medical testing and other fields	Mainly used in a single field	A wider range of applications

3. Technical details and practical applications

Baseline drift test:Through continuous measurement for 30 minutes, the deviation between the maximum, minimum and initial values of the fluorescence intensity is calculated. This method can effectively evaluate the stability of the instrument in long-term operation.

Minimum detection amount determination:The sensitivity is calculated by combining the standard solution dilution method with the peak height data. This indicator directly reflects the detection capability of the instrument.

Repeatability and long-term stability:Short-term and long-term performance are evaluated through 7 continuous measurements and 11 interval tests. This provides users with a comprehensive basis for quality control.
