PPSQ-51A/53A

Protein Sequencer

Analytical Stability and Higher Detection

Baseline Stability

PPSQ series protein sequencers separate PTH-amino acids isocratically. This improves baseline stability and allows high-sensitivity analysis of PTH-amino acids.

Retention Time Reproducibility

Isocratic sequence analysis provides more stable retention times. Therefore, peaks detected in previous cycles can be cancelled using substation chromatogram processing, making it easier to identify sequences.
