ASTM D5837 2-Furfural and Related Compounds HPLC Transformer Oil Furan Analyzer Model LC-4000

(LC-4000 Model)

1. P4000 High Pressure Infusion Pump

Introduction
P4000 infusion pump - high precision, high stability, high efficiency.
P4000 infusion pump is widely used in various fields of chromatography analysis. The experience and technology that P4000 infusion pump has obtained is applied to the development of new technology, which constantly enrich various functions that experiment requires .

Features
It adopts patent and exclusive technology of static motor control circuit, which can make the motor control signal automatically get feedback and track, improving the motor control accuracy and ensuring the reliability and stability of the pump.
Pump form: double-plunger reciprocating series or parallel
The patented technology of floating self-aligning seal technology andpump head self-cleaning extend the service life of the seal, and ensure the instrument is durable and cost-effective (online plunger seal cleaning (optional)).
Convenient and easy flow and pressure correction ensure high accuracy and stability of the instrument.
Two kinds of gradient operation program design are adopted: with linear gradient and step gradient to choose;
Programmed solvents and compression factor can be automatically compensated.
Complete pre-cleaning function can facilitate the replacement of the fast solvent.

2. Ultraviolet Detector UV4000

High sensitivity and higly cost effective;
Simple and compact structure;
Stable and excellent performance;
With functions of automatic event marking and zero setting of absorbance.

Main Features
Advanced optical unit design
The UV-4000 detector introduces a new idea in to its optical unit design. As we known, the principle of this kind of detector is based on Lambert-Beer law as the formula described below so the most important thing we want to do is to improve the light path, and get the biggest light source energy both in sample and reference photo-diodes.
Emphasis improvement:
1)Light source:
2)Light path
3)New design filter
4)Concave photographical grating
Advanced flow cell designed
All-out digital signal processing and controlling
New integrated Power-source module, ensure the system working more reliable.
