Product Description:
Agilent gas chromatographs have long been known for reliability, precision, performance and service life. Take your laboratory gas chromatography performance to the next level with this professionally refurbished Agilent 7890B Gas chromatograph (GC).
The Agilent 7890B gas chromatograph offers high performance chromatography with a full suite of performance enhancements, time and resource savings. The combination of precise pneumatic devices and temperature control enables extremely accurate retention time reproducibility, which is the basis of all chromatographic measurements.
Features:
Retention time locking (RTL) keeps the retention time constant between different samples, different columns, different instruments and different laboratories
Microplate flow control technology (CFT) provides unique instrumentation features such as multi-dimensional gas chromatography (GC-GC/Deans Switch center cutting), full two-dimensional gas chromatography with flow modulator (GC x GC), and pre -, mid -, and post-column blowback
Monofilament TCD provides a stable baseline with minimal drift without a separate reference gas or manual potentiometer adjustment
The FID, which automatically adjusts the detection range, enables detection and quantitative analysis from parts per billion (ppb) to parts per thousand in a single sample injection
The integrated SCD/NCD (sulfur or nitrogen chemiluminescence Detector) enables the detection, equimolar response and quantitative analysis of sulfur or nitrogen contaminants down to ppb levels in complex substrates
Helium saving modules and alternative carrier gas solutions significantly reduce the amount of helium used, increase the flexibility of laboratory analysis and save costs
The optional hydrogen sensor module Series 2 uses built-in intelligent diagnostics to continuously monitor operating status, detect hydrogen leaks early and turn off airflow, and only need to be calibrated every six months
