7090 SERIESNitrogen & Sulfur GC detectors

P r o d u c t f e a t u r e sPatented Pyro-chemiluminescent™nitrogen and sulfur technology

� one injection — two results

� add to FID for one injection — three results

� highly selective for nitrogen and sulfur

� equimolar response for all nitrogen and sulfur bearing compounds

Maximum uptime

� long-term operation on one calibration

� 14" dual zone furnace for optimal oxidation and reduction

� complete sample combustion enhances short- and long-term

stability, equimolarity, and selectivity

� long ceramic tube life: 6 –12 months

� oil-less vacuum pump operates maintenance-free for several years

The leadership continues…Building upon years of innovation, analytical leadership, and

customer satisfaction, Antek sets the standard for simultaneousnitrogen and sulfur GC detection.

Utilizing accuracy and precision of our Pyro-chemilumines-cent™ technology, the 7090NS Nitrogen/Sulfur GC Detectordelivers equimolar response for all nitrogen- and sulfur-containing compounds. Chemiluminescence is the clean, fast,interference-free method for determining all bound nitrogenand sulfur in a variety of matrices.

N i t r o g e n , N i t r o s a m i n e s , S u l f u rAntek Instruments, Inc. o�ers the most advanced detectors

for GC, SFC, and SimDis. With the Model 7090’s versatility,users can buy one detector now—nitrogen or sulfur—and addthe other later.

The Model 7090N Chemiluminescent Nitrogen Detector isspeci�c for nitrogen compounds and easily converts to nitro-samine-selective mode without any hardware change. TheModel 7090S Sulfur Chemiluminescent Detector is speci�c forsulfur compounds. Our Model 7090NS o�ers unprecedentedsimultaneous detection of nitrogen and sulfur compounds.

Conventional element enhanced detectors are less selectiveand therefore still have problems with interfering compounds.The 7090 Series eliminates those problems by detecting nitro-gen and/or sulfur compounds only—without halogen,phosphorous, or hyrocarbon interferences that have complicat-ed this work in the past. This unique detector also gives a linearresponse, and has sensitivity that is stable over time, providingmore reliable results.
