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.   

Simple, Easy-to-Use Data Analysis Functions    Specialized protein sequencer software makes it simple to perform the reprocessing of chromatograms, the overlay of multiple chromatograms, and the automatic estimation of amino acid sequences, which are required for sequence analysis.   

• Reprocessing of chromatograms required for data analysis   
• Overlay of multiple chromatograms   
• Automatic estimation of amino acid sequences   

Compliance with FDA 21 CFR Part 11    LabSolutions PPSQ software provides compliance with FDA 21 CFR Part 11 guidelines and enables compliance with the security, user management, and audit trail requirements specified by FDA 21 CFR Part 11.   

Security    Users are managed on the basis of groups, with each user being recognized by means of a username and password. Unique groups can be created by including persons having different access privileges. Clearly defining each user’s access privileges prevents unauthorized changes to settings, instrument operation, and data access.   

User Management    LabSolutions’ user administration comprises the setting of rights groups and assignment of rights to users just as in Windows. Access rights required for each user can be set by assigning various levels of access to each user. This helps achieve effective user administration and more efficient laboratory operations.   

Audit Trail    Logins and logouts to the system, changes in users and groups, and the start and completion of acquisition, together with the username and the time, are all recorded. The recorded operational log can be registered in the database to provide traceability.   

Software Validation    The integrity of the programs that comprise the system and the raw data acquired by instruments can be checked, ensuring the reliability of the system and data. The results of these alteration checks can be managed as printouts.
