Medium and low pressure preparative chromatograph

1. establish a new standard for rapid preparation of chromatographic performance

High performance, automatic identification of column size and packing type, and improvement of purification efficiency, whether it is purification of synthetic compounds, natural products, peptides or polymers. The system can identify chromatographic columns and supports, sense the amount of solvent and waste liquid, optimize separation conditions, and automatically clean the injection valve of solid loading. The built-in steam sensor can warn whether the solvent leaks. The steam hood at the collection support position is attached, so that the preparation chromatography can be used on the ordinary operating table.

2. powerful and easy-to-use software and single screen operation

The software is simple and intuitive without learning, and can start working in a few seconds. The chromatographic separation can be easily completed on the touch screen, which can effectively complete the purification, thus saving time and solvent consumption. Network connection login and control desktop separation. There is no need to be on duty. During operation, parameters, including solvent percentage, wavelength, flow rate and operation time, can still be modified without repeated purification.

Select normal phase or reverse phase column according to the type and quantity of purification target samples

Automatically identify column type and load operation parameters

Automatic connection detector (UV, VIS, els and MS)

Press start to load the sample to start automatic separation

3. intelligent support identification + Intelligent solvent level sensing radio frequency automatic identification and calling the optimized separation program to automatically record the use condition history and other information. Intelligent identification of multi-size collection support can be collected according to the appropriate volume

to avoid tube leakage or overfilling, and to avoid drying the chromatographic column or filling the waste liquid container, resulting in the loss of compounds.

4. the gold standard chromatographic column is higher than the ordinary one

Twice the separation efficiency of the chromatographic column - the purity of the sample can be as high as 98%

Separation of compounds with ARF <0.1, such as isomers

Avoid high back pressure resulting in longer operation time

On average, 60% of the purification time is saved, and 30% or more of the solvent is saved (Figure 1)

5. the solid loading ferrule has the functions of solid sample injection and self filling chromatographic column. It can be adjusted randomly according to the amount of sample or silica gel. It is well sealed without gradient hysteresis. Specifications: 5g, 25g, 65g.

6. built in detectors: uvnis ultraviolet visible light detection, ELSD evaporative light scattering detection, Ms mass spectrometry detection, etc

UV, uvnis photodiode array PDA detection technology, higher absorption detection dynamic range, adapt to more sample loading, realtime display of running and post running spectrogram, and collection according to purity index

ELSD evaporative light detector, built in integration, collects non chromogenic

groups or non-volatile compounds in a wide range,

providing scalability and sensitivity for loading high / low absorption compounds. All parameters optimize the separation conditions according to the solvent used. The molecular weight directional purification collection only collects the peaks that match the molecular weight of the target compound, eliminating the need for further analysis and saving the post-treatment time.
