Clarity
Chromatography Station
Clarity is an advanced chromatography station designed to acquire
and evaluate data from any commercially available chromatograph with
a standard analog output and from selected chromatographs with digital
output.
Up to four independent chromatography systems, each of which can
be equipped with up to four detectors, can be simultaneously connected.
The chromatography station package includes the Clarity Software
and an A/D converter internal PCI card or external USB box. |
Features
Measuring
Simultaneous data acquisition from up to four independent four-detector
chromatographs - 4×4 configuration
Integration
There is extensive possibility to modify chromatograms. The chromatogram
can be changed by entering global
parameters or interactively, through direct graphic modification of
the baseline.
Overlay
Simultaneously displays a virtually unlimited number of chromatograms
and their mathematical modification; for
example, mutual deductions or derivations of any order.
Calibration
Internal and external standard calculation methods, calibration of
groups of peaks and reference peaks method for better identification.
Automated measuring support
Sequence tables for any set of samples with or without an autosampler.
Postrun
Automatically displays, prints, exports and starts other programs
after the completion of a measurement.
Summary result
tables
Displays and prints selected results from all simultaneously displayed
chromatograms.
User settings
User selects parameters for peak display and the specification for
axes, including color from an extensive array of color settings. Text
labels and lines, either as part of the area or anchored to a chromatogram,
may also be inserted.
Export
Optional exportation of all results, with or without the chromatogram,
in various formats, into a file or clipboard.
Import
Imports chromatograms or mathematical curves, which have been saved
in text or AIA formats, from other programs.
Method
and calibration history
Each chromatogram can easily be displayed under the same conditions
as when it was printed, exported or saved.
Column
performance
Calculations of peaks in terms of symmetry, efficiency, resolution;
all by several methods (tangent, moments, etc.).
Batch
Automatically batch processes, displays, exports or prints any number
of chromatograms.
User calculations
Users can define custom calculations in the Result and Summary tables.
Using the integrated editor you can create your own columns from original
columns and individual mathematical functions.
User
accounts
Sets up access rights and passwords (including their parameters e.g.,
minimum length, validity, etc.). Each user can define his or her own
station appearance.
Audit trail
Records selected events and operations into a special file. Records
selected operations directly into a chromatogram.
Electronic signature
Each chromatogram can be signed electronically. Signature selection
is based on the username or the signature certificate.
Networked
Solution
Clarity chromatography station files can be accessed from networked
computers using Clarity Eval software. This enables the offline evaluation
of chromatograms, development of new methods and printing reports.
Clarity Screenshots
Instrument Window
The Instrument window is the control center of the whole process of
data acquisition and evaluation.
The Information Table displays the processed sample: Name, applied
template method, acquisition mode, etc.
The Status Line indicates the current state of the analysis: elapsed
time and state.
The Analysis-processing Diagram provides icons for fast access to
every process of the whole procedure.
Clarity Window
The Clarity window is an entrance point to individual chromatography
systems. Depending on the configuration users can acquire data from
up to 16 detectors configured on four independent Instruments.
Chromatograph Window
 The
Chromatogram window displays the chromatogram and results. Users can
easily edit acquired chromatograms visually in the graph or through
Integration table.
The Result tables (Results, Summary, Column Performance, etc.) can
be easily customized to display the data you want see exactly in the
way you want to see them.
The Summary tab displays data from overlaid chromatograms in one table
for easy comparison.
Calibration window
The Calibration window has two main screens, a global calibration
table and dedicated tabs for each compound (on the screenshot)
The compound tabs contain a table with concentration levels matching
the response with Amount and a calibration curve.
Any point can be temporarily suspended in the graph it is then marked
with a circle instead of a cross.
Digital Outputs
The A/D converters supplied by DataApex provide digital outputs that
can be used for Start synchronization with other devices.
These outputs can be also controlled from the Event Table.
Tutorials download
The tutorials present selected themes related with Clarity chromatography
Software. They will provide brief introduction into the topic. They
do not cover all the possibilities and functions of the presented
topic. Detailed and complete information can be found in the relevant

 Clarity
21 CFR Part 11 compliance
Clarity, Clarity EA and Clarity Offline softwares provide variety
of tools supporting the GxP practices. These tools enable to configure
the chromatography station in a way to comply with the requirements
of the 21 CFR Part 11 directive of the FDA. This ensures its suitability
for use in regulated environments.
Clarity Lite does not contain some these tools and so it is not recommneded for use in regulated environments.
Supporting tools for 21 CFR Part 11 requirements
1. Software Validation
Certificate of Software Validation is available upon request.
2. Installation Qualification
The Test IQ (Installation Qualification) is an integral component of the station. This test monitors that the software has been properly installed and the results can be accessed from a printed protocol.
3. Operational Qualification
Validator for OQ (Operational Qualification) is an optional package available for testing and validating the station. This is accomplished simply with the use of our chromatogram generator and a software utility.
4. Logon with Password
5. User Accounts
Selectable rights, unique user profiles This system allows to create a unique password protected profile for each user. The user profile then defines in detail the user's rights within the station (e.g. authority to effect changes in the methods of measurement) and may limit ones access to only certain connected instruments.
6. Password expiration and minimal length
7. Electronic Signatures
Electronic signature implemented. A user may sign his or her data. This electronic signature is stored with the name and date and supplemented with a set phrase (e.g. measured by, approved by, etc.). Two types of electronic signature have been implemented:
a) using user accounts
b) using a certificate
The signature information associated with the signing that indicates the printed name of the signer, the date/time, and the meaning, is included in any readable form of the records (see par 11).
8. Audit Trail
Audit Trail of whole system, chromatograms, calibrations and sequence. Audit Trails are part of corresponding files. Detailed logs and histories of modifications enable users to maintain an audit trail. The station documents all parameters describing the conditions and methods of data processing for the user. This allows for easy access to a complete profile of information regarding any prior modification's performance.
9. Record of all changes
History of all methods and calibrations as part chromatogram files
10. System Suitability Test
- method performance and system consistency monitoring
11. Printed reports
- page numbering, labeled with date and time of analysis and print out, includes information about applied electronical signatures. Reports can be printed to electronically signed PDF files. |
