LECO L-PAL3 GC Autosampler

Available exclusively from LECO, the L-PAL3 GC Autosampler is a highly robust, fully integrated autosampling platform designed for high flexibility and reliability in gas chromatography workflows. Based on proven CTC PAL3 technology, it supports discrimination-free ultrafast GC injections and minimizes carryover while ensuring precise and reproducible sample handling.

Key innovations include automatic tool exchange (ATX) for seamless switching between liquid, headspace, SPME, and ITEX sampling modes, vial bottom sensing to prevent mis-injections, and high vial capacity for unattended operation. These features allow analysts to focus on compound identification without downtime or uncertainty.

Key Features

• Allows for automation of up to 162 two mL samples, or 45 ten/twenty mL samples.
• Discrimination-free injection speeds with complete injection cycle time down to 100 milliseconds.
• Bottom-sensing technology ensures that even very small volumes can be sampled.
• Four separate models available so you may configure your package based on your autosampler needs.
• Automatic Tool Exchange (ATX) allows users to switch between liquid, SPME, and headspace seamlessly.
• 96 to 384 well plate sampling supported; requires foil cutter.
• Now available with Peltier cooled racks.
