XENON Series Xenon Lamp UV/Vis Spectrophotometer, Double Beam, 190–1100 nm

XENON xenon lamp UV/Vis spectrophotometer — double beam, 190–1100 nm

The XENON xenon lamp UV/Vis spectrophotometer combines double beam optics with a Hamamatsu xenon flash lamp. The lamp needs no warm-up, so the instrument measures as soon as it is switched on, and one source covers 190–1100 nm. Two models are available — XENON-200 with a spectral bandwidth of 2 nm and XENON-250 with 1 nm — both with scanning up to 3000 nm/min and a 10.1″ touch screen.

Double beam optics with a xenon flash lamp

Deuterium and tungsten lamps burn continuously and need time to stabilise before the first reading. A xenon lamp UV/Vis spectrophotometer works differently: the flash lamp is fired only during the measurement and reaches full intensity at once. In XENON the reference beam compensates pulse-to-pulse variations, so the baseline stays stable to ±0.0003 A per hour, with stray light ≤0.03 %T at 220 and 360 nm and noise of 0.0005 A at 500 nm.

Key characteristics

• Double beam UV/Vis spectrophotometer, grating 1200 lines/mm, wavelength range 190–1100 nm
• Hamamatsu xenon flash lamp — no warm-up; according to the manufacturer the lamp lasts at least 3 years
• Two bandwidth versions: XENON-200 2 nm (baseline ±0.002 A) · XENON-250 1 nm (baseline ±0.001 A)
• Wavelength accuracy ±0.3 nm, repeatability ≤0.1 nm; stray light ≤0.03 %T; stability ±0.0003 A/h
• Photometric accuracy ±0.002 A (0–0.5 A); photometric range −0.3 to 3 A; noise 0.0005 A at 500 nm
• Scanning up to 3000 nm/min, kinetics, quantitation, multi-wavelength and DNA / protein test; 10.1″ touch screen, USB and RS232

Suitable for

• Laboratories with occasional or interrupted measurements that should not wait for a lamp to warm up
• Pharmaceutical and quality control laboratories with UV/Vis methods and spectral scans
• Biochemistry and life sciences: nucleic acids and proteins at 260/280 nm, enzyme kinetics
• Environmental and water laboratories with UV methods such as nitrate
• Teaching and research laboratories that need one instrument for the whole UV and visible range

Why a xenon lamp UV/Vis spectrophotometer

A xenon flash lamp emits short, intense light pulses across the whole UV and visible range. Because it is fired only for the measurement, there is no warm-up period and no change-over between a deuterium and a tungsten lamp — the spectrum from 190 to 1100 nm comes from one source. The lamp works only while the instrument measures, which is why the manufacturer states a lamp life of at least 3 years.

For continuous routine work with deuterium and tungsten lamps choose the LEGEND or NOVEL-900; for the highest sensitivity in the UV choose the LEGEND-PMT with a photomultiplier detector — all in the menu above.

Knowledge base

Spectral bandwidth, stray light, Beer–Lambert law and the choice of cuvettes are explained on COLO.Science — UV-Vis spectrophotometry and colour measurement, our knowledge base; how absorbance fits among other laboratory measurements is described in Measurement in laboratory science. The full data are in the XENON technical specification (PDF).
