Fast, Reliable Answers

4The faster separations provided by narrow-bore capillaryGC columns are fully exploited when all sample-associated components of the system are miniaturized.The CP-4900s micro-machined injector and detector,together with a narrow-bore column, deliver rapidseparations of permanent gases and vapors.

Additionally, pneumatics for micro electronic gascontrol and flash memory to store current methodparameters are now integrated with the GC modulecreating plug-and-play GC channels.

Each GC channel is a complete miniaturized GC witha narrow-bore column for high efficiency separations.

Maintaining separation. 200 nL volume ThermalConductivity Detector (TCD)eliminates peak broadening.

More analyses in less time for tighter processcontrol. Backflush reduces the equilibration timebetween analytical runs for many sample types.

Increase Monitoring Frequency with Backflush Option

With micro-electronic gas control and time-programmableBackflush, you inject sample components of interestwhile eliminating contaminants.

Backflush prevents less volatile components and waterfrom entering the column. Baseline drift from latereluting contaminants is eliminated, and equilibrationtime between injections is substantially reduced.

Fast analysis and frequent process monitoring with theCP-4900 ensures high quality end products.

Microtechnology for Maximum Speed Improve data and process quality by frequent sampling

Analytical Cycle Time Comparison

Faster results with plug-and-play GC channels.One, two or up to four channels used in parallelfurther enhance analytical speed.

Efficient sample introduction. Siliconmicro-machined, variable volume injectorintroduces sample in narrow band.

5Reconfigure in MinutesAnd, easy maintenance when you need it

The CP-4900 delivers the results and ruggedness youdemand in the lab and in the field for the analysis ofgas and volatile liquid streams.

Quick and easy reconfiguration and repair withexchangeable GC channels and module sub-assemblies

Immediate start-up with Electronic Data Sheets(EDS) which store operational history and last-usedmethods

Refinery Gas

4-Channel SystemChannel A: Al203/KCl-PLOT

Less than 40 seconds. In this example,Channel A of a four-channel system separateshydrocarbons in a refinery gas mixture. A fullanalysis, including hydrogen, nitrogen, CO,and CO2, is complete in 200 seconds.

Fuel Cells

Better characterization in less time. Optimize Fuel Cell operation and design with informationgenerated by a two-channel CP-4900.

2-Channel SystemChannel B: PoraPLOT Q

Single-Channel SystemChannel A: MolSieve 5A PLOT

Accuracy, speed and profitability. Precise andfrequent gas mixture measurements are essentialto successful specialty gas manufacturing.

Complex samples such as natural gas and refinery gasare often analyzed on conventional multi-column,multi-valved gas chromatographs. With the CP-4900Micro-GC, a complete analysis is achieved withoutvalves and in a fraction of the time required with aconventional GC.

The compact CP-4900 analyzes complex gas samplesusing the selectivity of up to four independent GCchannels. Each GC channel, with a different columnphase, simultaneously separates a different subset ofsample components.

And, single or dual sample inlets and pumps, plusoptional gasifier for volatile liquids and pressurized gasstreams, enable the CP-4900 to handle a wide range ofsample types.
