COUNTER CURRENT & CENTRIFUGAL PARTITION CHROMATOGRAPHY, PLUS HPLC, IL-LC AND SFC
Together AECS-QuikPrep (UK) and Couturier (France) bring you World Leading products for
High Performance Liquid-Liquid Chromatography™ at scales from micro-gram to tonnes per annum
EasiSoft from Gyan
EasiSoft can operate both on-line (pump control and UV display for example), and off-line
Here is an overview of the features incorporated into the software.
Your 1st Choice for Preparative and Process Chromatography / Extraction
Continuous on-line monitor of UV output, pump gradient, pressure variation
On-Line pump control Via RS232 provides:
Start Pump (eg from autosampler)
Stop Pump (eg from fraction collector)
Start signal from pump (eg to fraction collector)
Synchronisation of master and slave pumps
Ready signals out
Automatic recognition of cartridge type and automatic set of optimum flow rate (requires
Signal output for valve switching (eg auto back-flush)
Signal output to flow divert valve (eliminates need for fraction collector for simple samples)
Output to solvent selection valve
Display of total working hours of pump
Alarm for overpressure
Graph of pressure variation (requires accessory)
Graph of gradient
Hold and re-start of gradient
Graphical gradient programming
Infinite programs in memory
All programs may be created within the software and downloaded to EasiFlash or EasiPump.
The same software can be used with all Gyan pumped products!
Helps the user develop new separations and purifications by:
Flash Chromatography simulation from TLC runs
Obtain simulated flash chromatogram using the same solvents and silica used in a TLC run.
Use to forecast good approximation of time to collect fractions
Contains a database of the most commonly used flash chromatography solvents. Containing
useful information such as eluting strength, density and other chemical and physical
properties important for the user and software. Uses may input their own solvents into the
Selection of alternative solvents
Once a separation is developed with a specific solvent mix, EasiFlash can calculate a new
mixture in which a solvent is replaced with another one providing the same eluting power.
Particularly useful if one solvent is unobtainable, dangerous or expensive!
Using data from a small column, it is possible to obtain the parameters necessary to scale-up
to a larger column and obtain the same separation
Loading of data from TLC runs
From the image of a TLC plate or data obtained from a small column, the predicted loading
capacity of all column sizes is available
Optimum flow rate calculations
EasiSoft will calculate the optimum flow rate to be used in different conditions to achieve the
best results with each cartridge size
AECS can offer "Total Preparative Solutions™" packages, and can therefore assist you in your
choice of the best preparative technology, be it Flash Chromatography, Preparative / Process
HPLC, or HSCCC, or even maybe a two / three dimensional combination.
AECS can also offer contract method development or final product preparation to non-GMP or
