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.

1. 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.

2. 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.

3. 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.

4. 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.

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

 

Simple, Easy-to-Use Data Analysis Functions

 

  • Chromatogram peak integration, printing, and other processes can be performed on a per-sample basis.

 

Simple, Easy-to-Use Data Analysis Functions

 

  • Displays multiple chromatograms. Analysis cycles can be updated simply by clicking a button.
  • Window allows easy identification of sequences.

 

Simple, Easy-to-Use Data Analysis Functions

 

  • Calibrates PTH-amino acid retention times.
  • Retention times can be edited simply by selecting a PTH-amino acid and clicking a peak.

 

Simple, Easy-to-Use Data Analysis Functions

 

  • Automatically generates a report containing analytical parameters, estimated sequences, yield rates, and other information.

 


Automatic Sequence Estimation
Sequences are automatically estimated after analysis of each cycle is complete. Up to four candidate amino acids are displayed together with their certainty levels.

Customized Reports
Reports containing information such as analytical parameters, estimated sequences, and yield rates are automatically created.

Yield Graph Display
Initial and repeated yield rates are calculated and displayed in graph form. Amino acids used for calculations can be freely selected.
 

Structure

Using Edman degradation, it derivatizes the amino acids of a protein in order from the N-termini, cleaves the derivatives, and from the HPLC retention times for these cleaved derivatives, identifies the amino acids.

Isocratic System

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.

Environmentally friendly eco-design

Performing PTH-amino acid analysis in an isocratic mode in which eluents are recycled to allow repeated use of the mobile phase makes it possible to reduce liquid waste and running costs.

Gradient System

High-Sensitivity Analysis

A high-sensitivity flow cell enables high-sensitivity detection of PTH-amino acids, which allows for sequential analysis using trace samples.

Analysis Stability

This system has high analysis stability because it is equipped with a high-performance detector and a solvent delivery pump that provides excellent pumping performance, even in the micro flowrate range, combine to ensure high analysis stability. Because chromatograms with good reproducibility can be obtained, peaks detected in the previous cycle can be canceled by performing differential chromatogram processing. This enables easy identification of PTH-amino acids even from trace samples.
