It fades. Sensitivity drops, noise increases, and your limits of detection quietly deteriorate until one day your method validation fails. Proactive lamp replacement is the simplest way to maintain data quality.  ![HPLC Blog 3 (900 x 300 px)](https://blog.chromatographydirect.com/hs-fs/hubfs/Canva%20images/HPLC%20Blog%203%20(900%20x%20300%20px).png?width=900&height=300&name=HPLC%20Blog%203%20(900%20x%20300%20px).png) --- ### Deuterium lamps: the UV workhorse Every UV and DAD detector relies on a deuterium lamp for wavelengths below 400nm. They're rated for a fixed number of hours (typically Standard Lamp 1000 - Long Life Lamp 2000), and performance degrades well before complete failure. Our Certus long-life deuterium lamps deliver 2000 hours of rated output for example: - **CD-5190-0917**: Long-life HiS D2 lamp (8-pin, RFID) for Agilent G7117A/B, G4212A/B - **CD-2140-0820**: Long-life D2 lamp (RFID) for Agilent G1315C/D, G1365C/D, G7115A, G7165A - **CD-2140-0813**: Long-life D2 lamp for Agilent G1315C/D, G1365C/D, G7115A, G7165A - **CD-G1314-60101**: Long-life HiS D2 lamp (RFID, VWD) for Agilent G1314D/E/F, G7114A/B - **CD-G1314-60100**: Long-life D2 lamp for Agilent G1314B/C We also stock lamps for all leading manufacturers ### Tungsten lamps: the visible range For visible wavelength detection (above 400nm), your DAD or VWD uses a tungsten lamp. Our CD-G1103-60001 tungsten lamp (1000hr rated) fits Agilent G1315C/D, G1365C/D, G7115A, and G7165A detectors. ### When to replace Don't wait for the instrument to tell you. Track lamp hours and order a replacement at 80% of rated life. A lamp running beyond its hours may still light up, but the spectral output becomes unstable, introducing noise that masks itself as method variability. ### Beyond lamps We also carry flow cells, flow cell gaskets, and detector electronics spares. For mass spectrometry systems, our range includes electron multipliers and filaments, the high-wear items that directly impact sensitivity and signal-to-noise ratio. The Home of Chromatography Consumables, and that includes every lamp, multiplier, and filament your detector needs.
