Lamps and Detector Supplies

Chrom Tech supplies genuine Agilent certified replacement lamps engineered for maximum sensitivity, long-term stability, and reliable detector performance in UV, VIS, and DAD systems. As an authorized Agilent distributor, we provide only OEM-certified lamps manufactured, aligned, and tested to precise optical and electrical specifications.

  • Every lamp is tested for noise, drift, operating voltage, light intensity, and optical alignment to ensure detector stability and reproducible results.
  • Improved coating technologies extend Agilent lamp lifetimes by up to 50%, minimizing downtime and replacement frequency.
  • Agilent’s deuterium lamps feature a narrow output aperture that increases light intensity and reduces baseline noise—delivering a significantly higher signal-to-noise ratio.
  • Enhanced sensitivity supports lower detection limits and more confident quantitation, with typical lifetimes exceeding 2,000 hours of operation.

All Agilent replacement lamps are manufactured in an ISO 9001–certified facility and are fully traceable throughout production. Each unit undergoes rigorous performance validation using NIST- and PTB-certified optical standards, ensuring compliance with Agilent’s strict detector requirements and guaranteeing dependable, long-term detector performance.

Key Definitions â–¸
Deuterium Lamp
A UV light source used in LC detectors to provide a stable, high-intensity baseline across low-wavelength regions. Agilent deuterium lamps are engineered to minimize noise and drift for sensitive UV quantitation.
Signal-to-Noise Ratio (S/N)
A measure of detector performance comparing peak height to baseline noise. Higher S/N improves detection limits and quantitation accuracy.
Optical Alignment
The precise positioning of the light source within the detector housing to ensure maximum intensity and minimal stray light—critical for reproducible detector performance.
ISO 9001 Certification
An international quality management standard ensuring consistent manufacturing processes, traceability, and rigorous documentation throughout lamp production.
NIST/PTB Traceability
A validation requirement indicating optical test equipment is calibrated against U.S. (NIST) or German (PTB) national measurement standards, guaranteeing accurate photometric performance.
Frequently Asked Questions â–¸
How long do Agilent deuterium lamps typically last?
Agilent certified lamps generally provide more than 2,000 hours of stable use. Enhanced coatings and narrow-aperture designs improve intensity and reduce noise, extending useful lifetime compared to non-OEM lamps.
Why should I choose genuine Agilent lamps over third-party alternatives?
Genuine Agilent lamps undergo strict testing for noise, drift, alignment, and operating voltage. OEM lamps provide higher signal-to-noise ratios, better sensitivity, and consistent detector performance—validated using NIST/PTB traceable standards.
How do I know when my detector lamp needs replacement?
Indicators include increasing baseline noise, loss of sensitivity, shifts in calibration, or detector warnings. Replacing the lamp restores optimal intensity and improves quantitation accuracy.
Are Chrom Tech replacement lamps genuine Agilent OEM parts?
Yes. Chrom Tech is an authorized Agilent distributor and supplies only certified OEM lamps that meet Agilent’s performance, alignment, and optical standards.
Do all detectors use the same type of lamp?
No. Deuterium lamps are used for UV detection, while tungsten or xenon lamps may be used for VIS or fluorescence systems. Always match the lamp model to your specific Agilent detector to ensure proper alignment and spectral performance.
