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.
