HPLC preparative
K-Prep
Accommodates preparative columns whose inner diameters range from 20-200mm. The purification of high-valued added substances is accomplished using K-Prep and chromatography packing material with particle sizes ranging from 5 to 20 um. The system is a fully automatic system with pressure limit of 100kg/cm2.
POINT
- Easy operation.
- Fully automated continuous operation via computer control.
- Precise and speedy isolation by isocratic or gradient elution operation.
- Economically efficient with recycle separation.
- Compact.
- Simple maintenance.
- Easy expansion.
- Comply with GLP/GMP validation.
USAGE
- Separation for peptides,proteins etc.
- Separation for intermediate of food products, pharmaceuticals and agrichemicals.
- Separation for fermented products.
Fully automatic operation
Mobile phase, pump, automatic injector, wash valve, column switch valve, recycle valve, fraction collector all operate by computer control. K-Prep software records the real-time chromatogram and pressure. Outstanding user friendliness and reliability by programmable logic controller (PLC) allows remote control over each unit of the system.
Manual control with easy operation
By clicking an icon on the PC display, the corresponding apparatus is manually adjusted.
K-Prep is a flexible system and can be used in a variety of chromatography modes.
It has a high rate of recovery and selectivity. It can meet various kinds of needs of the preparative liquid chromatograph.
Easy maintenance and expansion
Valves, pressure gauge, gradient mixers etc. are unitized to allow easy replacement in the unlikely event of a failure.
Pump can be easily pulled out by use of a slide rail for easy maintenance.
Up to 50mL(100mL) sample injection is possible
The automatic injector is equipped with 50mL(and/or 100mL) sample loop in conjunction with a high pressure 6-port valve and a syringe. The sample is drawn into the loop as many times as needed, using 25mL syringe (standard), so that the required quantity of the sample can be injected. When a large quantity of sample is needed, the injection should be carried out by means of a pump.
Powerful high precision pump unit
Adoption of double plungers and a high precision servo-motor minimizes pressure pulsations and allows high precision delivery of the solvent down to 1/1000 of the maximum flow rate.
Motor driven valve with low dead volume structure
The low dead volume structure permits quick solvent changeover and optimal gradient performance.
The thick orifice allow the mobile phase to moves very smoothly. YMC have developed
a special structure of air driven value which is superior in operability and
a device of unlimited drop system for fraction collector. The low dead volume
with washing capability will perform fraction with less contamination.
Compliance with GLP,GMP validation
- Comply with system validation when it is delivered.
- Comply with computer system validation when it is delivered.
- Records of operation necessary for GLP and GMP will be created automatically.
- The name of the file will not be overwritten after created mechanically.
- Security management is established including passwords and identification codes entry.
