"How many injections should I expect to get out of my reversed phase C18 HPLC columns?"
“Put simply, it depends. This is probably not the definitive answer you were hoping for but there are a number of different factors which influence the total number of injections that you can expect for a HPLC column. These relate to the actual column in question, the way you are using the column (the method operating conditions), and also the nature of the sample which is being injected.

The course is delivered using our virtual environment for learning, e-MTS, and consists of:
- A series of training videos (totalling over 3 hours where each video is approximately 25 minutes),
- Exercises on which you will receive feedback from your personal tutor and,
- An assessment which enables accreditation of the training - It is recognised by the Royal Society of Chemistry for the purposes of continuing professional development.
The cost of this course is only GBP £125 + VAT and includes a copy of our training book, An Introduction to HPLC for Pharmaceutical Analysis (which normally costs GBP £29.27). This is great value for a course which equates to a full day of training.
So, how does it work?
All you need is access to the internet. The training is undertaken over a period of 1 week. You sign up and select a week which suits you. Each day training videos and exercises are uploaded to your virtual classroom which you can watch and submit answers for the exercises. This allows you to access the training materials at a time which suits you within the 24 hour period (you should allow about 90 minutes since there are 2 videos, each of length approximately 25 minutes and the exercises should take about 40 minutes). At the end of each session feedback from your personal tutor and full solutions for the exercises is sent to you by email. The assessment is completed on the last day and a certificate is sent out for your training records.

A resource for chromatographers
As promised, the MTS HPLC calculator can now work out how much mobile phase you need to prepare for gradient methods. Simply fill in the gradient table making sure to match up A, B, C & D to the solvent lines on your HPLC instrument and include any solvent holds and re-equilibration steps at the end/beginning of each injection.
Let us know your suggestions for HPLC calculations that you would like to be added to the calculator.
