Product Short Description
Product Name
Agilent Technologies G1946-80060 fast polarity switching high-energy dynode power supply for LC/MS systems.
Product Introduction
This electrical assembly is an mass-spectrometer high-voltage power module used in Agilent liquid chromatography/mass spectrometry instruments. It provides fast polarity switching and high-energy dynode voltage for ion detection and signal optimization in single-quadrupole and triple-quadrupole platforms.
Description
Technical Specifications
Designed for Agilent 6100 series single-quadrupole and 6400 series triple-quadrupole LC/MS systems. Distributor documentation for related G1946-80060/B units lists bipolar output up to approximately -6 kV to +6 kV, output current around 10 mA, laboratory operating temperature 0 to 40 °C, storage temperature -20 to 60 °C, dimensions approximately 127 x 89 x 50 mm and weight approximately 0.5 kg. UNSPSC classification 41115700.
Function Features
Rapid positive/negative polarity switching, stable high-voltage regulation, low ripple dynode supply, compatibility with Agilent MS detector electronics and service replacement within qualified instrument configurations.
Application Scenarios
Pharmaceutical impurity and quantitation workflows, environmental residue analysis, food-safety testing, metabolomics and other LC/MS applications requiring alternating polarity or high-sensitivity ion detection.
Performance Parameters
High-voltage stability under mass-spectrometer vacuum and temperature conditions, fast settling during polarity reversal, controlled output current for dynode/electron-multiplier biasing and reproducible detector gain.
Material Composition
High-voltage transformer and capacitor assembly, precision regulator circuitry, insulated PCB, shielded metal or coated enclosure, connectors and cabling compatible with Agilent MS instrument compartments.
Structural Characteristics
Instrument-compatible power module format with high-voltage output terminals, control interface and shielding for minimal electrical noise. Designed for installation in Agilent LC/MS electronics stacks or detector chassis.
Working Principle
The module converts instrument low-voltage DC/supply rails into precisely regulated high voltage for the dynode or detector stage. Control electronics adjust output polarity and magnitude according to acquisition method, enabling positive/negative ion switching and consistent multiplier response.
Installation Requirements
Install only in the Agilent instrument model specified by the service manual. Use qualified metrology/service personnel, proper ESD grounding and correct high-voltage connector orientation. Verify firmware and instrument configuration after replacement.
Usage Precautions
High voltage presents shock and component-damage risk. Do not operate outside specified temperature/humidity. Confirm instrument series, option suffix and calibration requirements before commissioning. Inspect for damaged insulation, loose connectors and contamination before energizing.
