Selective Detectors

Specialized Selective Detectors for Advanced GC Analysis

Agilent’s gas chromatography detectors can dramatically improve your ability to detect compounds in matrix. Choose from a range of GC detectors, including flame ionization detectors (FID), thermal conductivity detectors (TCD) and electron capture detectors (ECD). For additional selectivity, we offer nitrogen phosphorus detectors (NPD) and flame photometric detectors (FPD) GC detectors. For greater selectivity and sensitivity, specialized chemiluminesence detectors for sulfur and nitrogen are used to detect trace levels of these impurities. Agilent works with a range of partners to provide detection systems to meet any gas chromatographic need.

Sulfur Chemiluminescence Detector

The reimagined and redesigned Agilent 8355 SCD represents the first major advance in sulfur chemiluminescence detection in 25 years, making the technology more reliable and easier to use. Highly sensitive and highly specific, the reimagined detector is also easier to maintain, thanks to a simplified burner design with 50 percent fewer components. The most common service routine, which used to take one hour, now takes only 10 minutes. The 8355 employs a dual plasma burner to achieve high temperature combustion of sulfur-containing compounds to form sulfur monoxide (SO). A photomultiplier tube detects the light produced by the chemiluminescent reaction of SO with ozone. This results in a linear and equimolar response to the sulfur compounds, without interference from most sample matrices

  • ● Sulfur-specific detection for gas chromatography (GC)

  • ● Fully integrated or standalone configurations available

  • ● Picogram-level detection limits

  • ● No hydrocarbon quenching

  • ● Linear, equimolar response to sulfur compounds

  • ● ASTM Methods compatible

  • ● Tandem SCD and FID operation

  • ● ~40% reduction in burner components; reduction of potential leak points

  • ● Inner ceramic tubes replacements is a 10 minute activity

Nitrogen Chemiluminescence Detector

The Agilent 8255 Nitrogen Chemiluminescence Detector (NCD) is a nitrogen-specific detector that produces a linear and equimolar response to nitrogen compounds. This is accomplished by using a stainless steel burner to achieve high temperature combustion of nitrogen containing compounds to form nitric oxide (NO). A photomultiplier tube detects the light produced by the subsequent chemiluminescent reaction of NO with ozone. Because of the specificity of the reaction, complex sample matrices can be analyzed with little or no interference.

  • ● Nitrogen-specific detection for gas chromatography (GC)

  • ● Picogram-level detection limits

  • ● No hydrocarbon quenching

  • ● Linear, equimolar response to organic nitrogen compounds

  • ● Responds to ammonia, hydrazine, hydrogen cyanide, and NOX

  • ● Redesigned Burner and Detector, the NCD also has a nitrosamines specific configured option

Micro-ECD

The Agilent micro-electron capture detector (micro-ECD), together with the Agilent 7890A, 6890N, or 6850N Series II gas chromatograph system, revolutionizes trace-level analyses of halogenated organic compounds and aromatic pollutants. Major design innovations neatly wrap ruggedness and reliability around unprecedented sensitivity and linearity. Spend less time maintaining the detector and more time running samples, with the Agilent micro-ECD.

  • ● Most sensitive ECD on the market

  • ● Detection zone volume 10 is times smaller than any other ECD; assures detection with extremely low concentrations, eg., less than 6 fg/mL of lindane

  • ● A broad dynamic linear range for confident, accurate quantitation of samples containing compounds with unknown concentrations, from femtograms to nanograms per microliter, eg., 5 x 105 for lindane, with true linearity of 5 x 104

  • ● Compliant with U.S. EPA Contract Laboratory Program linearity requirements for pesticides over a range of 1 to 500 picograms/microliter

  • ● Higher linear velocities through the detection zone reduce analyte residence time, decrease the chance of cell contamination, and improve uptime

  • ● Hidden anode minimizes the chance for contamination to reach the anode

  • ● Optimized electric field minimizes contamination effects on cell performance

  • ● Replaceable liner that serves as a physical stop for the column: ensures reproducible column installation and decreases column contamination of the cell

  • ● Variable sampling rate from 5 to 50 Hz makes it ideal for fast chromatography

Blos Nitrogen-phosphorus Detector (NPD)

Nitrogen-phosphorus detectors (NPD) for gas chromatography are specific to nitrogen- or phosphorus-containing compounds and are well suited for environmental and forensic applications. The key component to NPD performance is its bead. Agilent has acquired the worldwide manufacturing rights to the Blos bead for Agilent NPD. The Blos bead’s very high operational stability and long lifetime has been available in Europe - now Agilent is making this technology available globally. The Blos bead for the Agilent NPD is based on a high-performance glass material technology. When compared to the legacy white ceramic bead (also sold as an Agilent NPD option).

  • ● Longer bead lifetime (more than 2x)

  • ● More stable operation throughout the bead’s lifetime

  • ● For nitrogen containing compounds – similar sensitivity and selectivity specifications

  • ● For phosphorous containing compounds – superior sensitivity and selectivity specifications

  • ● Superior resistance to ambient humidity and moisture
