CP-3800 GC : A modular and powerful gas chromatograph for high-precision analyses
The CP-3800 GC from Varian is a powerful and modular analytical instrument designed to meet the most demanding requirements of modern laboratories in the field of gas chromatography. Its design is based on an expandable architecture that allows full customization of the system according to the specific needs of each application. With the ability to accommodate up to three injectors and three detectors operating simultaneously, it offers exceptional flexibility, enabling users to optimize productivity while maintaining high analytical precision. Its robust frame and thermal stability ensure consistent performance even in high-throughput environments.
One of the CP-3800’s major strengths lies in its adaptability to a wide range of analytical methods, thanks to a broad selection of injector and detector options. It can be configured with split/splitless, PTV, flash megabore, or on-column injectors and paired with detectors such as FID, TCD, ECD, NPD, or PFPD, thus covering applications ranging from VOC detection to trace quantification in complex matrices. The Quick-Switch system allows instant configuration changes without complex reprogramming, making it easier to switch between analytical methods within the same lab.
Operationally, the CP-3800 has been designed for ease of use, smooth operation, and advanced automation. It can be operated locally via its LCD display or remotely using Varian Star or Galaxie software, which allows intuitive management of sequences, analytical parameters, and data acquisition. Electronic Flow Control (EFC) ensures precise and reproducible regulation, with accuracy up to 0.1 psi. The column oven supports fast temperature ramps—up to 100 °C/min—and can operate in extreme ranges from -99 °C to +450 °C depending on the analysis requirements. These features ensure optimized cycle times and effective separation even in the most demanding analyses.
Lastly, the CP-3800 can be integrated with several automation solutions such as the CP-8400, CP-8410, or Combi PAL autosamplers, allowing for unattended injection of dozens or even hundreds of samples. These systems support standard liquid injection, solid-phase microextraction (SPME), and both ambient and heated headspace modes. The ChromatoProbe further extends the system’s capabilities by allowing direct analysis of solid or liquid samples without prior preparation. This adaptability, combined with measurement precision and ease of use, makes the CP-3800 an essential tool for laboratories that demand performance, reliability, and flexibility.
