Autosampler Guide

Autosamplers are commonly coupled to analytical devices to quickly and accurately load samples for analysis. Austosamplers can be equipped to perform simple liquid, solid, headspace, or solid phase microextraction (SPME) injections.

6 Questions to Ask When Buying an Autosampler

  1. Is the autosampler compatible with your current analytical instruments?
  2. How many samples can the instrument accommodate? Can you expand this number?
  3. What is the injection volume range of the autosampler?
  4. Which injection method does the instrument use?
  5. What range of speeds are available for injection? What is the maximum back pressure during injection?
  6. Which samples is your instrument capable of analyzing? Is the instrument designed for liquid or headspace injection?

Safety Tip

A common issue with autosamplers is leaks. Problems such as usage of the incorrect needle or blockage of the waste line can result in samples and waste leaking from the autosampler. Uncontained leaks may expose the operator to hazardous materials without their knowledge. Autosamplers are available that can detect leaks and handle them safely, keeping the users safe. This is done by siphoning leaks into a single tray and triggering an alarm when the instrument detects liquid in the tray.

Maintenance Tip

Autosamplers come with comprehensive maintenance schedules and instructions. By following the instructions and timeline for your instrument, lab members can perform weekly, monthly, and annual maintenance without a service provider. This will help your lab save money on a service plan. Service providers can be contacted for more complex issues or if you are not comfortable replacing parts on the instrument.
