Agenda

• Introduction• How to get it right the first time• Thermo Scientific™ Dionex™ Chromeleon™

Chromatography Data System (CDS) tools for RFT analysis• System Suitability Tests• Intelligent Run Control• Summary

3

Introduction

• Modern business drivers are continually pushing to reduce the time it takes to get a product or service to market, reduce the risk and cost associated with that, and to improve quality

• In laboratories, delivering an analytical result that’s ‘right first time’ (RFT) is the answer• No reprocessing data or re-running injections

• No out of specification (OOS) results or reporting/calculation errors

• Getting RFT analysis automatically gives: High quality of results and confidence in results Lower cost of analysis Improved lab efficiency Faster release to market and return on investment (ROI)

How to Get It Right the First Time?

• Robust and reliable instrumentation• Qualification automation

• Monitor instrument status

•Robust, reproducible, and reliable methodology• Standard operating procedures

• Method validation

• Automated sequence creation

• Run-time checks

• In-run reactions to actual chromatographic results

• Automated result calculation and export

• Operators• Make learning curve as shallow as possible

• Provide tools to help inexperienced users with more complex tasks

Chromeleon CDS Tools for RFT Analysis

• Instrumentation• Predictive performance – instrument qualification, service and wear part

monitors

• Methodology• ICH Method Validation Templates

• eWorkflows™

• Sequence Ready Check

• Smart Startup

• System Suitability Test (SST) with Intelligent Run Control (IRC)

• Spreadsheet-based Report Designer with integral Report Check

• Operators• All the above combine to ensure ANY operator can achieve RFT

analysis

System Suitability Tests

9


• USP Chromatography General Chapter:• "System suitability tests (SST) are an integral part of gas and liquid

chromatographic methods. They are used to verify that the resolution and reproducibility of the chromatographic system are adequate for the analysis to be done. The tests are based on the concept that the equipment, electronics, analytical operations and samples to be analyzed constitute an integral system that can be evaluated as such.“

• Ensure performance of complete testing system (including instrument, reagents, and columns) is suitable for intended application on a day-to-day basis • System must pass set of predefined acceptance criteria before sample

analysis can commence

• USP and ICH guidelines are “bibles” followed closely by industry

10

• Commonly used to verify, for example:• Peak resolution

• Column efficiency

• Peak asymmetry

• Injection repeatability

• Capacity factor

• Signal-to-noise ratio

• Standard correlation

• Performed before and throughout analysis

• Data acceptance criteria describe limits used to accept or reject analytical data• Represent minimum acceptable system performance levels


11


• Setup SSTs to ensure chromatography quality

• Templates for most common tests

• Evaluate SST results offlineor as samples are analyzed

• Any measurable parameter can be monitored• Can also check results against

specifications

12


• Easily create multiple tests

Identify test injections

Define evaluation parameters

Select required test type

Customize parameters

Select test component(s)

13


• Create complete set of tests• Can directly view test results

• In Processing Method

• In report

14


When SST fails:• “Analyst facing initial SST failure should stop sequence

immediately, before any sample injections have been done, to avoid having to retest sample”

• Analysis of actual samples should only commence after system has passed all SST limits, not only failed criteria

• Automation makes this very difficult• Systems often run unattended overnight

• Analyst sees failure too late

• Most CDS offer SST tools to monitor but what are options when tests fail?• Often only abort/continue

15

Intelligent Run Control

16


• Can you react to changing conditions during the sequence? What if your RTs drift or the %RSD is out of spec? Can you re-inject a bad injection?• Usually left to analyst to decide – subjective, error prone & often too late.

• Chromeleon Intelligent Run Control (IRC) allows decisions to be made during run• Improves analytical efficiency

• Improve or standardise product quality

• Reduces solvent and sample use

• Reduces results review process

17


• Actions evaluated for Pass and Fail tests• Insert injections

• Re-inject partial or full sequence

• Autodilution

• Perform arithmetic processes

• Extract channels or Optimum Integration Pathfrom a PDA 3D Field

• Actions performed conditionally or unconditionally

18

Intelligent Run Control - Examples

• Component Carry Over• Test: Is area of main peak < 0.0040 % for a blank injection?

• Pass Action: Continue

• Fail Action: Insert blank injection in sequence, and inject

• RSD of Peak Area• Action: Calculate RSD of peak area of main peak in 6 SST injections

• Test: Is RSD > 1%?• Pass Action: Abort

• Fail Action: Continue

19

• 2 extra columns are visible in the Processing Method• Double click any column to edit test

• Access to relevant part of wizard from column clicked


20

• Configure pass and/or fail actions – multiple actions are possible


Specify multiple actions

Select required action

21


• Error handling for a failed execution allows user to continue to next action/test case/injection or abort

22


• Example of an Unconditional Action• Will not be evaluated on test results

• Set desired action and then set properties for that action

23

• New IRC action in 7.2 SR1 – AutoDilution• Customize parameters for re-injection

• Select a different Instrument Method

• Alter any editable injection parameter including Custom Variables


24


• Example: Re-inject check standards if ‘Peak Area RSD’ fails

25

• In-run SST checks to your specification• High confidence in your results – no reprocessing saves time and effort

• In-run IRC reactions to OOS results• No need for re-runs – saves time, solvents and consumables

• Fewer OOS investigations – saves time and effort

• Gives more right first time analyses

Summary

28

Summary

• System Suitability Tests• Ensures performance of system on a day-to-day basis

• Can check all aspects of analysis

• Multi-component, multi-parameter testing

• Can check conformance to specification

• Gives confidence in results when all pass

• Intelligent Run Control• Automates handling of OOS results

• Can react to passed and/or failed conditions

• Multiple conditional or unconditional actions

• Eliminates wasted reinjections, solvent, sample and time

• If sequence completes all tests have passed results are OK

29

Summary

• RFT needs preparation and reproducibility• Automation where possible

• Chromeleon CDS Software provides:

• Predictive Performance• Improves instrument utilization and uptime analysis

more likely to complete first time

• ICH Method Validation Templates• Ensure method is robust and suitable for the intended

analysis more likely to run first time

• eWorkflows• Create complete, correct sequence with predefined files

and well-defined structure correct sequence first time

30

Summary

• Sequence Ready Check• Ensures all sequences are correctly configured and ready

to run first time sequence will run to completion

• Smart Startup • Automatically initializes instrument & sets correct initial

conditions first injection is always good

• System Suitability Tests• Check all aspects of analysis including results against

specs highest confidence in results

• Intelligent Run Control• Take automated, in-run actions based on actual results RFT results, no OOS investigations
