General Analytical

Significant Figures and Rounding (HTML)
Free!

This course is free! Do you want to see what our web-based training courses are like? This is your chance to learn how effective on-line learning can be. Significant figures is an important aspect whenever you are reporting numerical data. In this course we will review the common rules for significant figures and rounding, and discuss how these rules can be applied to common laboratory procedures.

Approximate Time Required:
15 minutes

Media Used:
.jpg, .gif, .wav

Students will learn:

  • The rules for determining significant figures in mathematical operations
  • How to estimate the number of significant figures associated with certain laboratory procedures
  • The proper way to round "5's" (many people are doing it wrong!)

Laboratory Skills

Propagation of Errors/Preparation of Standards (HTML)
$49
This course introduces the concept of propagation of errors as it applies to the preparation of analytical standards. The student is presented with a simplified version of the concept, along with estimated error values for common laboratory procedures. From this information, the student will learn how to calculate the total error for a given analytical procedure. Finally, different dilution schemes (parallel, serial, and combined) will be introduced and discussed. Review questions are provided at the end of the course to help assess your understanding of these concepts.

Approximate Time Required:
1 hour

Media Used:
.jpg, .gif, .wav

Students will learn:

  • Types of errors in laboratory procedures.
  • How errors are combined in consecutive procedures.
  • How these can errors be estimated.
  • How to select dilution schemes (parallel, serial, combined).

Using Pipetting Instruments (HTML)
$29
This course provides an introduction to the use of manual pipetting instruments. General design features are discussed for air displacement and positive displacement models. The student will learn the assumptions that must be satisfied to properly use these instruments. Finally, common problems and their solutions will be discussed. General instructions for calibration are also provided.

Approximate Time Required:
45 minutes*

Media Used:
.jpg, .gif, .wav, .mpg

Students will learn:

  • Key design features of pipetting instruments.
  • The nine critical operating assumptions that must be satisfied to get the best accuracy.
  • Common problems and how to avoid them.
  • How to calibrate pipetting instruments.

Chromatography

Extra-Column Effects Calculator (HTML)
Free!

This tool is free! Extra-column effects add to the observed peak width (and decrease the number of theoretical plates). (This topic is discussed in detail in the on-line course on Understanding Modern LC Systems.) This calculator lets you estimate the magnitude of these effects. The user can enter values for the following parameters:

  • Column efficiency (number of theoretical plates)
  • Connecting tubing internal diameter
  • Connecting tubing length
  • Detector flow cell volume
  • Detector flow cell path length
  • Injection volume

The observed efficiency (number of theoretical plates) is then displayed, along with some other similar calculations. Using this tool will help you get the best performance from your LC system.

Approximate Time Required:
10 minutes

Media Used:
.jpg, .gif

Students will learn:

  • The relative impact of changes in connecting tubing, detector flow cell, and injection volume.

Introduction to the LC ChemStation-Part 1 (PowerPoint)
$49 (Download)

The ChemStation is a powerful program, but it's complexity can make it difficult to use. This introduction to the software will discuss:

  • ChemStation 'Views'
  • Editing Methods
  • Setting Up and Running Samples
  • Single Runs and Sequences
  • Loading Signals

After payment you will be able to download this presentation as a PowerPoint file for your personal use. The file includes "Notes" which can be printed. The notes contain more information than the static HTML courses, but not as much as the narrated versions. This format is best for self-study, not group learning.

Note: this course covers the standard ChemStation interface for LC instruments through version A.10.02.

This course should be completed before Part 2.

Approximate Time Required:
1 - 2 hours

Media Used:
PowerPoint

Students will learn:

  • How the ChemStation is organized, and how to get the system ready for analysis.
