CDS Analytical products

We manufacture Empore discs to provide a large surface area for sorbent/sample contact during SPE. The cation exchange sorbent contains selectivity for cationic analytes, such as primary, secondary and tertiary amines. Fast flow rates along with high throughput may be realized with Empore solid phase extraction disks.riod. Bake cycles can be delayed. Options include cryofocusing at the GC injection port and reactant gas.

The CDS Model 4000 Pyroprobe is specifically designed for users that occasionally need pyrolysis to assist their work in Pyrolysis - Gas Chromatography - Mass Spectrometry (Py-GC-MS). The 4000 has an economical price tag, and possesses a direct GC injection port mount feature to simplify the operation and installation. Installation and removal only takes minutes on conventional GC. 

The CDS Model 6150 Pyroprobe is the basic model of CDS`s 6th generation Pyroprobe. The 6150 connects to any model GC with a heated sample line for easy on/off installation. Low thermal mass programmable interface allows for thermal desorption of volatiles before pyrolyzing the sample.

The CDS Model 6200 Pyroprobe adds in an analytical trap to enable collecting analytes using slow rate pyrolysis. The built-in trap also expands the capability to use a reactant gas (like oxygen and air), and perform thermal desorption on sorbent tubes or larger samples. The 6200 also permits direct pyrolysis to the GC in GC carrier gas.

The Drop-In-Sample-Chamber (DISC) is a novel accessory module for the 6000 series Pyroprobes. It transforms the horizontal sample loading probe used in traditional manual pyrolysis system to a convenient vertical loading system. The DISC saves your precious time by reducing the sample tube loading process. When used with the filler rod, the DISC helps to reduce sample preparation time by skipping the quartz wool insertion. The DISC chamber also isolates the pyrolysis sample tube from touching the platinum heating coil and can help to eliminate coil damages.   

With the Dynamic Loading Sequence Table (DLST), the 6000 series autosampler module provides hands-free and worry-free analysis for an infinite number of samples. The autosampler has 47 positions with capability to add samples on the go. The autosampler is driven by a novel hybrid mechanism, combining the reliability from the state-of-art air actuators and the precision from electronic step motors. DISC option is required to be installed with the autosampler module.

The CDS HPR Pyroprobe enables users to study both high temperature and pressure in a micro-scale environment, with the convenience of results sent directly to their GC/MS. The unit is built on 5200 platform with a backpressure regulator and heated catalyst bed. Samples can be pyrolyzed at max 500 PSI (3400 kPa), passed through a user-selectable catalyst bed, and collected onto the built-in trap.

The 8500C delivers the same combination of quality that made the 7000 series such a reliable instrument, but with plug and play connectivity to the CDS 8500A autosampler. The 8500C features the foam sensor, an inert coated wet trap and a 8 port pneumatics systems, all providing the highest available performance and unrivaled chromotographic resolution.

The 7000C delivers the same combination of quality that made the 7000E such a reliable instrument, but with plug and play connectivity to the worlds leading autosampler platform - the CTC PAL Robotic systems. The 7000C features our industry standard foam sensor, a newly designed wet trap and our distinguished exchangeable sample pneumatics systems, all providing the highest available performance and unrivaled chromotographic resolution.

The 8500A autosampler is a 110 position autosampler with dynamic headspace sampling function for EPA methods 524, 624 and 8260 (both water and soil), and built on our 3rd generation autosampler with a faster and smarter sample loading. A perfect match for the 8500C Purge & Trap concentrator with integrated software control.
