Protein sequencer PPSQ-31A/33A model

Reliable technology with sales performance of 300 units (PPSQ series) in Japan, and new software that is easier to use.

On the basis of the traditional PPSQ series functions, the dual system software of the original PPSQ system and HPLC system is integrated into a programmable logic controller through newly developed sequence software, making it easy to select/input analysis conditions, reaction steps, and analysis results on one screen. In addition, when running amino acid sequencing, important chromatographic reprocessing can be performed through a newly developed programmable logic controller, which can process multiple chromatograms separately according to sample units, greatly improving data analysis capabilities. Moreover, if an HPLC analysis system is used, it can reduce noise levels and perform high-sensitivity detection of PTH amino acids.

Protein sequencer PPSQ-31A/33A modelfeature

1. High sensitivity detection
By reducing the noise level, high-sensitivity detection of PTH amino acids can be performed (noise level 0.5 × 10-5AU: single detector)

2. HPLC analysis system used
UV-VIS detector SPD-20A
Liquid delivery unit LC-20AT

3. Stability of analysis
Under the same intensity elution mode, the stable baseline for PTH amino acid analysis makes it easy to identify sequences in trace sample analysis.

4. Newly developed software
Newly developed software that improves operability and enhances data analysis capabilities.

5. Analysis of PTH amino acids eluted with equal strength
The PTH amino acid analysis carried out by equal intensity elution through the circulation of eluent can achieve "stability of retention time", "convenient maintenance of HPLC" and "reduce operating costs". Moreover, the mobile phase can be reused, thereby reducing waste liquid.
