KMPI - B Multi - parameter Chemiluminescence Analytical Testing System
Product Introduction
The KMPI - B multi - parameter chemiluminescence analytical testing system is a high - performance analytical testing device based on the Windows operating platform. It can perform various chemiluminescence detections such as flow injection chemiluminescence, static injection chemiluminescence, capillary electrophoresis chemiluminescence, capillary electrophoresis electrochemiluminescence, electrochemiluminescence, electrochemical analysis and detection, capillary electrophoresis electrochemical detection, microfluidic chip chemiluminescence, and microfluidic chip electrochemiluminescence.
Applications
Research on chemiluminescence mechanisms and methods.
Research on chemiluminescence applications.
The high - efficiency separation of capillary electrophoresis and the highly sensitive detection of chemiluminescence are well combined, realizing the integration of separation and detection of complex samples and greatly shortening the sample pretreatment time.
The KMPI - B multi - parameter chemiluminescence analytical testing system consists of six parts: an electrochemical analyzer, a multi - functional chemiluminescence analyzer, a numerical control capillary electrophoresis high - voltage power supply, a multi - channel high - voltage power supply for microfluidic chips, a flow injection sampler, and a multi - functional chemiluminescence detector.
A brief introduction to each component of the instrument is as follows:
Electrochemical Analyzer
The electrochemical analyzer provides electrochemical methods such as potentiostat, cyclic voltammetry, and linear sweep required for electrochemical and electrochemiluminescence analysis, as well as electrochemical current detection means. This part is the core of the entire testing system. The instrument is internally integrated with a standard USB interface for communication with the system computer, which can effectively complete the data transmission between the system computer and other instruments and corresponding control components.
Multi - functional Chemiluminescence Analyzer
The multi - functional chemiluminescence analyzer can control the signal transmission and negative high voltage of the photomultiplier tube, and can perform two detection methods: intensity detection and integral detection. The parameters of chemiluminescence (measurement time, sampling rate, amplification factor, etc.) can be set according to the program.
Numerical Control Capillary Electrophoresis High - voltage Power Supply
It provides the high voltage required for capillary electrophoresis analysis. The electrokinetic injection time and injection high voltage, as well as the analysis time and analysis high voltage can be independently controlled according to the program.
Multi - channel High - voltage Power Supply for Microfluidic Chips
It provides the electrophoresis power supply required for microfluidic chip analysis. This power supply can provide 4 - 8 channels of high - voltage power supply according to usage requirements. Each channel of power supply can complete high - voltage output, grounding, and floating control of any value according to the program design.
Flow Injection Sampler
The sampler is equipped with two sets of five - channel peristaltic pumps and two 8 - way two - position sample - changing valves. The system computer can set a multi - step control program to control the running time, running speed of the peristaltic pumps, and valve positions, and can complete various flow injection analyses such as flow injection analysis, continuous flow analysis, discontinuous flow analysis, and stopped - flow analysis.
Multi - functional Chemiluminescence Detector
It can perform various luminescence detections such as flow injection chemiluminescence, static injection chemiluminescence, capillary electrophoresis chemiluminescence, microfluidic chip chemiluminescence, and electrochemiluminescence, and can also be used as a shield for electrochemical detection to shield the influence of external electromagnetic interference signals.
