Wayeal Ion Chromatography Instrument for Environmental Water
Quality Analysis
Introduction of Ion Chromatography Instrument
Ion chromatography instrument is a type of high performance liquid
chromatograph, so it is also known as high performance ion
chromatography (HPIC) or modern ion chromatography, which differs
from traditional ion exchange column chromatography mainly because
the resin has a high cross-linkage and low exchange capacity, and
the injection volume is very small.
Features of Ion Chromatography Instrument
1. The integrated design and compact layout minimise the
connections between the components, reducing the dead volume of the
system and ensuring superior chromatographic performance.
2. 7.0" high brightness LCD touch GUI controller, synchronised with
the chromatography workstation, allows full operation of the
instrument and spectrogram display etc.
3. acid and alkali resistant materials such as PEEK, PTFE, PP and
other plastics are used for the drenching liquid storage, liquid
circuit piping and joints.
4. Full plastic colour identification of high and low voltage
pipelines for easy identification of the customer's operation and
improved self-protection of the system
5. Built-in column temperature chamber to shorten piping
connections and reduce dead volume and peak spread within the
system.
6. Precision temperature-controlled conductivity detector, user can
set the temperature according to their actual working environment.
