Character – Powerful
Accuracy and Stability
- “Accuracy is the spirit of analysis.” Based on
a well structured design and manufacturing process, unquestionable accuracy
and precision were a prerequisite, secondly quantification and precision of
analysis were dependent on accurate flow rate.
- Excellent reliability and stability. The pump heads have
been machined using a first class CNC process; the innovative structural
design has been designed to achieve minimum pressure fluctuation.
Consequently stable flow, low noise and overall quality provide the
foundation for reliable results.
- LCW software offers complete control, powerful data
processing, reporting functions, intelligent diagnostic systems and
maintenance utility ensure a complete and flexible software solution for
your analytical work.
- Art combined with practicality. The modular system provides
shape and character whilst being aesthetically pleasing. The unique and
practical design ensures ease of use and maintenance. In essence, the
combination of art and practicality complement each other.
- The HPLC-4 is a high performance yet cost effective
solution. The modular design ensures that you can configure the system to
meet your application requirements. A dedicated team of product specialist
will provide technical support and provide an application development
- The quotation that you would receive for HPLC-4 is for a Basic HPLC System. For each special parameter test, please refer to optional parts pricelist and inform us to add that parts to your quotation.
The figure above shows comparison of 10 injections (Response time 0.1s). From
this figure we can see that the Pump P-21 exhibits good
repeatability on both retention time and peak area, which leads to accurate
results. The solvent system incorporates a fluid design that uses a serial flow
path. The system employs dual plungers and two check valves for enhanced
reliability. The dual com gear is calculated to ensure optimal flow control
whilst an integral seal wash system will extend the serviceable life of the
pistons and seals.
Optimized solvent delivery is achieved
using pulse dampening compensation. This system optimizes pump
stability and decreases pressure ripple to 1%.
Accurate gradient elution: composition
Minor change composition down to 1% can be distinctly observed. DETECTORS
Simplified optics: comprising of an
advanced ellipsoidal mirror and concave grating. Compared with
traditional configuration, this arrangement greatly reduces the
number of optical components ensuring wavelength accuracy.
Transmission deuterium lamp
combined with tugsten lamp provides a wavelength range of
190-800nm. The shine through deuterium lamp eliminates moving
components, reduces noise whilst offering increase reliability.
The lowest baseline noise
<0.75x10-5Au allow sensitive analysis to be achieved. The
thermostatic flow cell reduces the influence of room
temperature and fluctuations on absorbance and provides a
Linearity range >104.
Low noise and drift noise <
0.75x10Au (25, 234 nm, dry cell, response time 1s)
Drift < 10-4 Au/h (25, 254nm, dry cell response time 1s)
Integral large capacity memory, which
can save the data in the event of accidental power shortage.
