Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6890A / 7673 #293778235 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6890A is a high-performance, multi-channel gas chromatograph (GC) spectrometer used for gas chromatography applications such as environmental compliance, process control, and a wide range of other laboratory techniques. This advanced spectrometer is equipped with superior features such as fast response time, reproducible performance, and excellent data quality. HP 6890A is designed to achieve excellent detection limits for trace concentrations of various organic compounds, and additionally, it comes with an advanced foreline-degassing system, which helps interface the GC to other instruments and avoids contamination of sample vapor streams. It is capable of flexible control, reliable performance, and superior data accuracy, making it an appropriate choice especially for industrial labs. AGILENT 6890A uses a high-resolution quartz crystal microbalance (QCM) technique for measuring mass flow rates in multiple channels. The spectrometer is equipped with a gas inlet system consisting of a heated transfer line, a pressure-tight splitter, and a graphite furnace. This ensures the concentration levels of each component sample remain unchanged throughout the chromatographic process. 6890A utilizes an innovative thin-film detector to monitor a wide variety of gases, including both light and heavy hydrocarbons. It applies advanced phase temperature programming, oven ramping, and manual control of the inlet temperature to monitor the purity of sample peaks. This spectrometer is also capable of separating polar compounds, thus making it suitable for a range of analyses. KEYSIGHT 6890A is outfitted with a thermal conductivity detector (TCD) to increase the sensitivity of environmental monitoring. This detector provides an enhanced baseline stability, temperature homogeneity, and low noise compared to traditional TCD systems. It also offers a large dynamic range as well as significant drift reduction. HEWLETT-PACKARD 6890A spectrometer delivers superior performance for analytical and process control operations. Its fast response time, reproducible performance, and excellent data quality make it an ideal choice for laboratories requiring accurate, sensitive, and reliable results.
