Why choose us?

We are a manufacturer and supplier of gas chromatographs and associated components and accessories and have been serving our customers worldwide for over 30 years.

Our instruments are known for their reliability, providing good reproducibility of analysis results even under heavy daily usage.

Our prices are much lower than other GC manufacturers, but without sacrificing capabilities.

Our instruments are designed for self-installation and self-maintenance, so maintenance costs are very low. Our software is included and license free.

Our instruments are compact, suitable for labs where space is limited.

Our instruments are easily transportable, perfect for satellite projects or mobile use.

We offer highly discounted educational models suitable for use in schools or undergraduate classes.

We encourage the use of Hydrogen as a carrier wherever possible, to avoid the growing cost of Helium. We offer a Hydrogen generator to remove the need for external gas supply.

We are experts in determining the applicability of our wide choice of detectors, columns and injectors to your needs, including their limitations and interactions. Call or email us with your requirements and we will work with you.

All components have a 2 year warranty, but you can talk to us for support without any time limits.
