Secrets of OpenLab ChemStation - Part 1: Understanding the Interface

OpenLab CDS ChemStation (the C version) looks similar to the old "B" version, and there are many similarities for many functions. However, with new hardware options and software features, there are some important differences in the C version. We will review both the old and new features along with some practical advice for getting the most from your software.

This webinar provides a nice introduction to the specific concepts discussed in Parts 2 - 4

Topics:

  • Control Panel and Starting the ChemStation
  • General ChemStation Organization
  • Using the Run Queue
  • Data Analysis Tasks
  • Review and Report Layout
  • Method Setup Screens

Who should attend?

  • Users switching from version B to C.
  • New ChemStation users
  • Any user who wants to upgrade their skills

Secrets of OpenLab ChemStation - Part 2: Integrating and Calibrating

Generating reliable chromatographic information requires that all peaks be integrated properly. The ChemStation has powerful and flexible integration capabilities, if you know how to use them. Too many users are still using manual integration because they have never been trained on the simple process of setting up the integration settings. We will show you how, and give examples for more complex chromatograms.

Similarly, ChemStation has always been able to perform many common calibration calculations for you, if you know how to set up and configure the system. (It is easy, but not always intuitive.) We will help you with both issues.

Topics:

  • Integration
  • What is integration?
  • Integration options for ChemStation
  • Adjusting integrator settings for complex samples
  • Calibration
  • Calibration basics
  • Setting up ChemStation calibration tables
  • Calibration table options
  • Using calibration information in ChemStation reports

Who should attend?

  • Anyone who wants to eliminate manual integration and save considerable processing time
  • Users who want to eliminate their external spreadsheets and all the problems that go with manual data entry.

  • Some experience with Visual Basic will be helpful, but not necessary. Users who have used the functions in Excel usually are able to use the system effectively.

Best Practices in HPLC Column Selection

  • Confused about which column to use for your HPLC method?
  • Not sure why a particular column was chosed?
  • Want to find an equivalent column, or a better column, or a different column?

The C18 column is the most popular option for HPLC methods, but is it the best choice for your method? There are many other options, and we will help you understand why some columns work well while others do not. This presentation uses our own research along with publicly available resources to help you understand how to begin the column selection process.

Topics:

  • What is selectivity?
  • Reversed phase vs. HILIC vs. mixed mode
  • Measuring selectivity
  • Selectivity resources and databases
  • Examples

Who Should Attend?

  • Method development staff
  • Researchers who want to better understand column selectivity
  • Supervisory staff

HPLC Basics for Quality Staff and Auditors

Chromatographic data are used to answer critical questions - drug purity, content uniformity, impurity levels, etc. The language and practices of HPLC are complex and not always completely understood, even by users. Review of these data sets often is performed by auditors who do not have a laboratory background in these techniques and discussing the results with chromatographers can be difficult if you don't speak the "language of chromatography."

This presentation provides an introduction to HPLC with an emphasis on understanding the language and practices that an auditor needs to properly review chromatographic data. Topics will include a discussion of the components and how their failure can affect results, a review of common chromatographic problems, and suggestions for dealing with problems.

Topics:

  • Brief introduction to chromatography and HPLC
  • Brief description of HPLC components and their associated problems
  • The language of chromatography
  • Checklist for reviewing data
  • Basic troubleshooting - what happens when a component fails
  • Investigating problem data
  • Real-world examples

Who should attend?

This seminar is for auditors, other Quality staff, and supervisors who do not have a technical background in chromatography, but must review and approve chromatographic data.

Making HILIC Work For You (FREE!)

Hydrophilic Liquid Chromatography (HILIC) is a relatively new operating mode in HPLC. Unlike reversed phase methods, we do not have 30 years of experience, and thousands of applications to help us learn about this new approach to separating polar, water-soluble compounds.

Attend this free seminar to learn more about how HILIC works, and how you can get it to work in your lab.

Topics:

  • What is HILIC?
  • Retention mechanisms in HILIC mode
  • Retention patterns
  • Operating suggestions
  • Limitations of HILIC

Who should attend?

This seminar is for method develop staff and HPLC analysts who must use HILIC methods, or want to learn more about this technique.

Reducing Integration Errors In Chromatography - Part 1: When Peaks Are Approximately the Same Size

Integration of chromatographic peaks is a critical step in the generation of chromatographic data. Errors in integration will result in a corresponding error in calculated results. Unfortunately, most analysts have little or no training in the proper procedures for peak integration. We will first discuss, in general terms, how integrators work. Then, peak integration issues will be examined using sets of real chromatographic data to illustrate when to use different integration strategies (drop, valley, etc.). We will discuss a variety of situations involving poorly resolved chromatographic peaks, when the peaks are about the same size.

Topics:

  • Introduction to chromatographic integrators
    • How do they find the peaks?
  • What does resolution mean when the peaks are not of equal size?
  • What integration baseline options are available?
  • Integration errors for each baseline option and recommendations for selecting the best option.
  • Sources of integration errors
    • Why are the numbers wrong?
  • Discussion - Questions and Answer

Who Should Attend?

  • All chromatographers can benefit from this presentation.
  • Reviewers will also find the content to be useful.
