ZHK3170 Dual-Channel Ion Chromatograph

The Dual-Channel Ion Chromatograph is a specialized instrument developed by our company to meet the detection needs of both high and low concentration samples across various fields. It features a dual-channel detection mode that allows for simultaneous analysis of different anions-anion, anion-cation, or cation-cation pairs under varying elution conditions. 
Compared to single-channel instruments, this design effectively doubles the efficiency. With its automatic range adjustment, it can accommodate samples of varying concentrations, reducing the need for dilution of high-concentration samples, simplifying pre-treat-ment procedures, and minimizing errors in detection results. This makes it the preferred equipment for inorganic ion analysis in various monitoring fields.

Main Features
● PC Chromatography Workstation + Mobile APP.
● Dual-channel operation, independently running detection analysis system can effectively double work efficiency.
● Flexible configuration options allowing for combinations of“anion + cation,”dual anions, or dual cations.
● Requires only one workstation and one PC, saving space and reducing costs.
● Precise and stable temperature control system that is unaffected by environmental temperature changes. Quick stabilization without long waiting times.
● Wide temperature control range with excellent stability (conductivity cell ±0.001℃, column temperature box ±0.01℃).
● Bipolar conductivity with dual-pulse detection. Automatic range adjustment with a broad range. Automatic temperature compensation with adjustable coefficients.
● Excellent linearity with a wide linear range (ppb-ppm), low noise, superior detection limits, and great repeatability. Sample acquisition frequency and filtering time can be set according to user needs.
● Circulating electrolysis regeneration suppressor, eliminating the need for regeneration liquid, high suppression capacity, automatic regeneration, rapid balancing, and long lifespan.
● 1-inch high-definition LCD touchscreen with integrated mirror glass for a wide field of view, sensitive touch response, intuitive display, and convenient operation.
● Error prevention design with user-friendly parameter setting reminders, minimizing the risk of incorrect operations. Adjustable backlight brightness and duration settings.
● High-pressure PEEK pump with dual pistons and electronic damping, enabling precise and stable flow with low noise and automatic piston cleaning. 
● Electric six-way valve for accurate and convenient operation.
● Degassing pump for online degassing to prevent bubble fluctuations. Switch valve for complete closure of the flow path to eliminate micro-flow.
● Peristaltic pump, which can be used for cleaning as well as replacing syringe injections.
● Dual pressure limit detection, leak detection, rinsing solution residual detection, overheating detection, user error detection, and fault detection.
● Suppressor over-voltage, over-current detection, and dry burn prevention.
● Recording of usage counts and duration for the pump, valves, columns, suppressors, and rinsing solutions.
● Audible and three-color light alarms. Temperature-controlled cooling fan.
● Online filter to protect the column and facilitate cleaning.
● Rinsing solution preheating lines for preheating before entering the column.
● Intelligent power on/off functions with remote control capabilities. One-touch quick access (power on, run, shut down, sample injection, cleaning, upgrade).
