Key Definitions â–¶
Ion Injector
A precision-machined LC/MS source component that directs ions from the spray chamber into the mass analyzer. Clean, correctly aligned ion injectors help maintain sensitivity and peak shape.
Electron Multiplier
A detector module that amplifies ion signals through a cascade of secondary electrons. Worn multipliers can reduce sensitivity, increase noise, and impact quantitative accuracy.
Nebulizer Needle
The component that delivers liquid to the spray chamber to form the initial aerosol in ESI/APCI sources. Proper nebulizer needle condition supports stable spray performance and ionization efficiency.
Gas Purifier
A trap used to remove moisture, hydrocarbons, and other contaminants from nitrogen or other gas lines. Clean, dry gases help improve ionization stability and reduce baseline drift.
Source Longevity
The operational life of LC/MS ion sources, influenced by cleanliness, replacement part quality, and environmental contamination. Genuine Agilent parts help maximize uptime and stability.
Frequently Asked Questions â–¶
How often should LC/MS source components be replaced?
Replacement frequency depends on sample load, solvent cleanliness, and ion source type. High-use systems may require more frequent replacement of nebulizer needles, capillaries, and ion injectors to maintain sensitivity and peak stability.
Why is it important to use genuine Agilent LC/MS supplies?
OEM parts ensure correct materials, geometry, and electrical behavior. Non-Agilent components may reduce ionization efficiency, alter calibration, or cause premature detector wear. Chrom Tech supplies only Agilent-certified components for guaranteed compatibility.
What causes loss of sensitivity in LC/MS systems?
Common causes include dirty ion injectors, worn electron multipliers, clogged capillaries, and gas impurities. Regular source maintenance and timely replacement of consumables help restore optimal response.
When should LC/MS gas purifiers be replaced?
Replace purifiers when breakthrough indicators activate or when baseline drift increases. Clean, dry gas reduces contamination and supports long-term mass spectral stability.
Are Chrom Tech LC/MS components genuine Agilent OEM parts?
Yes. Chrom Tech is an authorized Agilent distributor and provides only OEM-verified LC/MS supplies, ensuring correct materials, performance, and full instrument compatibility.
