Product Description
Instrument Introduction
The BIKAI Autosampler is a high-efficiency, intelligent gas bag autosampler designed for use with gas chromatography (GC). It automates sample line cleaning, sample loop cleaning, gas bag cleaning, and gas sample injection, significantly improving workflow efficiency. The system includes dedicated PC control software, allowing users to operate the autosper directly from a computer for enhanced convenience and speed.
Key Features
User-Friendly Operation – Simplified PC software eliminates complex parameter settings.
Versatile I/O Ports – Compatible with GC systems from various manufacturers.
Compact Circular Design – Saves bench space with its efficient sample loading structure.
Dual-Position Sensing – Ensures precise valve switching accuracy.
Modular Design – Supports unlimited module expansion for increased sample capacity.
Integrated Cleaning Function – Performs gas bag cleaning in addition to sample injection.
Durable Switching Valve – Features a PEEK valve body and PI valve core for extended lifespan.
High-Quality Gas Lines – All tubing is made of PTFE or PEEK, meeting national gas sampling standards.
Flexible Sampling Options – Each port supports quick switching between gas bags and syringe injection.
High-Concentration Detection – Automatically stops injection upon detecting high-concentration samples, initiates GC column heating, and purges contaminants for full automation.
