Introduction

This specification mainly refers to the GB/T 29248-2012 "Basic electrophoresis device", JJG124-2005 ammeter, Voltmeter, power meter, and resistance meter." This specification is the first release. Calibration Specification for Plate Electrophoresis Apparatus

1 Scope

This specification applies to the calibration of the measurement performance of the plate electrophoresis apparatus (horizontal plate electrophoresis apparatus and vertical plate electrophoresis apparatus). Other types of electrophoresis apparatus can be performed with reference to this specification.

2 references

This specification refers to the following documents. JJG124-2005 Ammeter, Voltmeter, Power Meter and Resistance Meter JJF 1071-2010 Rules for the preparation of national metrological calibration specifications GB/T 29248-2012 Basic electrophoresis device For dated references, only dated editions apply to this specification; all undated references The latest version (including all amendments) applies to this specification.

3 Terms and units of measure

3.1 Drift drift The amount of change in the output voltage or current of the electrophoresis device per unit time under specified operating conditions. 3.2 Electrophoresis bands electrophoresisspectrum The band formed by the sample on the carrier after electrophoresis. 3.3 Migration distance migrationlength The distance between the center of the electrophoresis band and the center of the sample hole in electrophoresis is specified in millimeters.

4 Overview

Electrophoresis refers to the phenomenon in which a charged particle moves toward an electrode under the action of an external electric field in a dispersed system. Electrophoresis devices use charged particles such as nucleic acids, proteins and other substances with different charging properties and move under the same electric field conditions. The principle of different directions and mobility is to implement the instrument for the separation and identification of charged particles. The electrophoresis apparatus is usually divided into There are two types of horizontal plates and vertical plates, which are generally made up of main parts such as power supply and electrophoresis tank, as well as auxiliary parts such as glue and cooling parts. composition.
