Scouting Gradients Calculator
Download this Excel method development spreadsheet to help select conditions for initial gradient scouting runs and to interpret the scouting run results.
On-line texts and courses:
- Analytical Training Solutions: A fully on-demand, self-paced learning library covering HPLC, GC, MS, and CE for all levels of experience.
- High-Performance Liquid Chromatography On-Line Course: Shulamit Levin. Also check out the rest of her site; lots of useful information and links about chromatography as well as about chemistry in general.
- Basic Liquid Chromatography: Yuri Kazakevich & Harold McNair. This has been a “work-in-progress” for some time; it is continually being improved and updated. A good, thorough treatment.
- Chromatography: From Dyer Laboratories. This is a brief text-only overview designed to provide background for technical translators.
- Reverse-phase HPLC Basics for LC-MS: from Ionsource. The title says it all.
- Chrom-Ed Series: Chromatography: By R.P.W. Scott. From The Library for Science. Reads very much like a print text converted to pdf format.
- HPLC e-learning from Academy Savant: Not free, but very well done and worthwhile self-paced training modules.
Basics (for students)
- Chromatography: It’s just a box: Basic definitions and explanations. Especially good for high school students.
Magazines & Journals
Most analytical chemistry journals include liquid chromatography papers. These journals and magazines listed here specialize in chromatography.
- Separation Science: Publishers of on-line and e-mail newsletters on chromatography and related techniques
- LC-GC: This site also has a large number of links to additional chromatography information.
- Journal of Chromatographic Science
- Journal of Chromatography
Discussion Groups (US)
The US has a number of local/regional discussion groups that focus on chromatography. These groups usually have regular meetings, and their web sites are often extremely valuable reference sources.
Message Boards and on-line discussion groups.
You can learn a lot about HPLC just by “lurking”, but don’t be afraid to post questions and, as you get experience, to answer questions posted by others. We’re all in this together!
- Chromatography Forum: We may be just a tad prejudiced (we host this one), but it’s a great site, with great give-and-take from users.
Other Chromatography Links
We’re not quite sure how to categorize these, so let’s just say they are repositories of useful information, including even more links:
The LC Troubleshooting Bible: A compendium of John Dolan’s “LC Troubleshooting” columns in LC-GC Magazine from 1983 through 2016 with index and keywords.
HPLC Simulator: a free, online resource for High-Performance Liquid Chromatography (HPLC) simulation, education, and more..
USP Column Equivalency Application: Two databases comparing selectivity of different HPLC columns.
HPLC Columns.org: Selectivity measurements on almost 700 columns from > 30 manufacturers
Some Useful Links for Chromatogaphers: From Douglas D. Frey, Professor, Department of Chemical & Biochemical Engineering, University of Maryland Baltimore County
Mass Spectrometry and Biotechnology Resource: An extensive compilation of information about mass spec.
A “Little” Mass Spectrometry and Sailing:A personal site belonging to James Little with a lot of useful information and links on GC-MS and LC-MS
Chemistry Resources: Heretical as it may seem, there is more to chemistry than just chromatography. This site belongs to Carlos Lopez of Universidad de Antioquia (Columbia) and has a tremendous set of links.
Manufacturers & Suppliers
If you hadn’t already guessed, instrumentation and supplies for HPLC is a big business. For convenience, we’ve tried to subdivide the manufacturer’s links into Instruments, Components and Accessories, Columns, and Supplies, but you should recognize that there is a tremendous overlap in these categories.
