Product Description
High-Performance Liquid Chromatography (HPLC) is a highly precise and widely used analytical instrument for qualitative and quantitative analysis of organic compounds in liquid samples. Utilizing high-pressure elution and high-efficiency chromatographic separation technology, the instrument separates target components according to differences in molecular polarity, adsorption capacity, and retention time, achieving accurate detection of trace and conventional substances in complex sample matrices.
This modular HPLC system consists of a solvent delivery unit, sample injection unit, column temperature control unit, high-sensitivity detection unit, and professional chromatography data workstation. Equipped with an independent screw direct-drive dual-plunger pump and valve-free automatic purging design, it delivers stable flow rate output, extremely low pressure pulsation, and excellent repeatability under full pressure and full gradient conditions. The ultra-low dead-volume flow path and high-precision optical calibration system effectively reduce extra-column diffusion, ensure sharp and symmetrical peak shapes, and greatly improve detection sensitivity and resolution.
T75 Solvent Unit
1. Solvent
remaining volume monitoring function to avoid solvent depletion
Built‑in sensor monitors mobile‑phase
remaining volume in real‑time.
2. Side‑shift door
design for convenient maintenance
Cabinet side‑shift door conceals pipelines
for a cleaner appearance and simplifies instrument maintenance.
D75 Detector Unit
1. Flexible multi‑detector
expansion for various sample types
Supports special detector expansion and
hyphenated configurations, including VWD, DAD, ELSD, RID, FLD, CAD, etc.
Compatible with micro flow cell, analytical
flow cell and semi‑preparative flow cell.
2. Ultra‑low dead‑volume
design for sharper peaks
Optimized micro flow cell, system flow path
(ID 0.12 mm) and zero‑dead‑volume high‑pressure hand‑tight fittings greatly
reduce extra‑column effects, improve detection sensitivity and deliver better
peak shapes.
3. High‑accuracy
full‑range wavelength calibration
Multi‑point linear wavelength calibration
using holmium glass ensures high wavelength accuracy across the full
measurement range.
4. Human‑machine
interactive touch screen for separated operation‑monitoring
Large‑size color touch screen synchronized
with the Labmate CDS workstation.
Enables off‑instrument laboratory
monitoring of instrument status, one‑click purging and syringe degassing
operations.
P75 Pump Unit
1. Valve‑free
automatic purging to reduce maintenance cost
One‑click automatic purging at the control
terminal enables true unattended remote operation. Valve‑free purging design
effectively lowers maintenance expenses.
2. Independent
screw‑direct‑drive dual‑plunger pump: superior accuracy over full pressure and
full proportion ranges for reliable method reproducibility
Stroke adjustment combined with precise
logic control of high‑speed solenoid valves guarantees accuracy and consistency
across full pressure and full proportion ranges. Suitable for standard HPLC and
UHPLC set‑ups.
3. Pulsation‑damper‑free
design for faster pressure ramp‑up and stable baseline
Real‑time stroke adjustment via pressure
feedback achieves extremely low pressure pulsation over the full pressure
range.
Pulsation‑damper‑free construction delivers
faster pressure build‑up.
LabMate CDS — Your trustworthy lab partner

heat‑exchange for fast equilibration
Innovative thermal‑exchange design provides
tighter contact between pre‑heating block and Peltier element for higher heat‑exchange
efficiency.
2. Multi‑column
& multi‑valve expansion for complex separation requirements
Optional switching valves enable 2D‑LC,
column switching, column back‑flushing, on‑line solid‑phase extraction, dual‑column
cyclic separation, flow‑path switching and other separation‑analysis modes.
3. Intelligent
tracking of column usage to prevent column performance degradation
Automatically records injection count,
analysis pressure and other column‑related data to support column‑replacement
decisions and service‑life assessment.
Compatible with chromatography columns of
any brand.
S75 Sample Injector Unit
