The Cobra Autosampler: What Are Its Benefits?

An autosampler automates the liquid sampling process by operating on a programmed time schedule, or in relation to conditions that are interpreted by sensors. In either case, autosamplers improve the efficiency of gas chromatography (GC) sampling – a process in which inlets were once filled by hand. Today, scientists can choose between several makes and models of autosamplers, of which the Cobra L / S liquid sampler is one of the best. Featuring a simple, lightweight design and easy operating procedures, this autosampler offers the following benefits, among others:

Features an All-Electric Design that Eliminates the Need to Purchase Gases

The equipment's all-electric design allows laboratories to reduce operating costs by eliminating the need to purchase a carrier gas for the mobile phase. For large laboratories and facilities that contain multiple laboratories, this can create meaningful savings.

Has Variable Injection / Syringe Fill Rates to Meet Process Requirements

Some autosamplers have a limited range of injection and syringe fill rates, but the Cobra autosampler has a range that accommodates that most demanding process requirements. Regardless of the GC sampling process you implement, this autosampler can meet its injection / syringe fill needs.

Uses Standard Syringes Instead of Proprietary Syrings

Ideally, an autosampler should use off-the-shelf syringes and not proprietary ones. In addition to costing more than off-the-shelf syringes, proprietary syringes are difficult to supply on an emergency basis.

Has RS-232 Capability for Data Output to Computers

In scientific instruments, an RS-232 connector – as opposed to the universal serial bus – is the preferred method for outputting data to computers, where it can be analyzed and archived.

Provided air gapping for added network security

Air gapping is an added network security measure that prevents sensitive data from being stolen and repurposed. Whether your GC data is proprietary or confidential in nature, air gapping offers the ultimate protection by physically, electronically, and electromagnetically separating your network from non-secure networks.

Offers wide syringe ranges between 5ul-250ul

A wide syringe range is recommended for laboratories that perform a variety of GC processes that require a varying range of syringe sizes. The 5ul-250ul range of the Cobra autosampler is ideal.

Comes with an Easy to Control User Interface

The easier an autosampler interface is to operate, the more efficient the GC process becomes. The Cobra autosampler features a simple keypad design that allows you to set the equipment to your particular GC process with ease. The interface control parameters are thoroughly explained in the owner's manual.

Features Multiple Tray Settings

In anticipation of various GC parameters, the Cobra autosampler features three levels of tray settings: 120 vials at 1.8ml per vial, 220 vials at.8ml per vile, and 60 vials at 10ml per vile.

Conclusion

The Cobra autosampler is designed to automate every GC process and integrate seamlessly with GC equipment. In doing so, it delivers the benefits listed above, among others.
