This specification applies to the calibration of micro-spectrophotometers. For other types of spectrophotometers, refer to this specification.

2 Reference documents

This specification refers to the following documents. JJG178-2007 Verification Regulations for Ultraviolet, Visible and Near Infrared Spectrophotometer GB/T 26810-2011 Visible spectrophotometer For dated reference documents, only the dated version applies to this specification; for undated references The latest version (including all amendments) is applicable to this specification.

3 overview

The volume of the micro spectrophotometer is small and the sample amount is small [(1~2)μL]. It is composed of light source, monochromator, absorption cell, The detector and signal indicating system consist of five parts. The principle is based on the selective absorption of light of different wavelengths and Lambert-Beer (Lambert-Beer) law for quantitative analysis and qualitative identification of substances, commonly used in nucleic acids and proteins Qualitative and quantitative analysis and quantification of bacterial concentration. The mathematical expression of Lambert-Beer law is. When testing, use a pipette to drop (1~2) μL of the sample onto the testing platform, and the instrument will automatically complete the test and display Shows the absorbance value and gives the qualitative and quantitative results of the sample (nucleic acid, protein and fluorescent dye).
