Flame Ionization Detector (FID) and 1079 (Programmable Temperature Vaporizing) Injector
CP-3380 Gas Chromatograph General Description:
Designed for basic gas chromatography applications, the affordable CP-3380 gas chromatograph, from Varian, is a fully functional system based on the revolutionary CP-3800 gas chromatograph. Like the CP-3800, this entry level model features the industry s largest display and full Ethernet communications using industry-standard protocols. While the CP-3800 gas chromatograph is flexible enough to support complex configurations, the CP-3380 is a simple, single or dual channel designed primarily for ease-of-use, and it s priced accordingly.
In addition, the CP-3380 gas chromatograph can be automated with the CP-8400 or CP-8200 Autosampler for high levels of productivity and is fully compatible with the powerful Windows -based Star Chromatography Workstation.

1079 Programmable Temperature Vaporizing (PTV) Injector General Description:
Delivers the Ultimate Chromatographic Performance
* Allows maximum flexibility
* Provides highest analyte recovery
The injector is a critical component of the Gas Chromatograph, influencing accuracy, precision, resolution, and analyte recovery. For over 15 years, Varian has pioneered capillary injector technology with a line of GC inlet systems that set the industry standard for injector performance.
The 1079 PTV represents the latest evolution in Varian's injector technology - extending the benefits of Varian's patented Septum-equipped Programmable Injector (SPI), to include split and splitless injection.
Representing the ultimate Universal Capillary Injector, the 1079 PTV delivers improved chromatographic performance and increased GC up-time, is compatible with the full range of open tubular columns, and is capable of isothermal or temperature programmed operation.
Five modes of operation: split, splitless, temperature-ramped splitless, Large Volume Injection (LVI), and cold on-column; allow maximum injector flexibility.
* New temperature-programmable on-column mode optimizes the recovery of polar and thermolabile compounds.
* Large-volume injections in temperature-ramped splitless mode means less sample preparation and increased sensitivity.
* Manual or electronic control of gas flow guarantees optimum retention time reproducibility.
* A new insert sealing design enables easy insert removal and replacement.
* A unique inlet design for unparalleled system inertness allows analysis of even the most thermolabile compounds.
The 1079 PTV is designed with ease-of-use in mind - whether making an injection, replacing an insert, or changing a column. The unique injector switch starts the GC and data system automatically, eliminating the need to press a start key, and improving retention time reproducibility.
The easy-to-access septum support captures the insert and ferrule, simplifying replacement. The optional "quick-connect" kit - which includes a fixture for measuring column insertion depths - makes column replacement easier. Choosing Varian's Advanced Electronic Flow Control System eliminates the need for external flow meters, streamlining setup and operation.
The 1079 PTV injector flow path has been designed to maximize recovery of a wide range of analytes in either the split or splitless mode. The optional Low Internal Volume, high-performance insert minimizes sample contact with the inlet surface, and provides cold on-column injector performance. All inserts are deactivated to Varian's strict specifications.
The 1079 PTV injector is an integral component of the Varian 450-GC Gas Chromatograph, delivering unmatched precision for greatest confidence in analytical results. The use of highly stable pneumatics provides state-of-the-art retention time and peak area reproducibility in all injector modes.

Flame Ionization Detector (FID) General Description:
The FID is used for the determination of most organic compounds. Faster separations and me accurate results often depend on small details. The FID has a patented, inert ceramic flame tip that significantly reduces peak tailing and partial loss of polar or higher boiling analytes.
