Installation and Training

Installation and Training

We encourage you to take advantage of Pickering Laboratories’ individualized two or three-day installation and training courses. For an all-inclusive fee we can provide post-column system installation and training at your site by an experienced chemist from Pickering Laboratories. The training includes performing analyses, routine maintenance and troubleshooting, and chromatogram interpretation.

Some of our authorized distributors offer their own training and installation services. Pickering has trained many local service engineers, and supports them fully on behalf of our distributors and re-sellers.

Whenever you buy installation and training by Pickering Laboratories, please call Technical Support early to schedule our visit to your site. This is especially important if you buy installation through a distributor, because we need to hear all the details directly from you. (Sometimes our distributors forget to tell us vital information like names, telephone numbers and delivery dates.)

Individually-tailored courses are also given at our facility in Mountain View, California. Please telephone or fax with your requirements, and we will advise cost and schedule.
