PMT sensitivity and xenon-lamp optics in a touch-screen double-beam instrument
Series overview
Optics, light source & detector
- Double-beam optical system with a 1200 lines/mm grating; wavelength range 190–1100 nm.
- Photomultiplier tube (PMT) detector — highly sensitive to light in the ultraviolet, visible and near-infrared ranges.
- Light source: xenon lamp / tungsten-halogen lamp; scanning speed fast / medium / slow.
- Automatic wavelength setting; accuracy ±0.3 nm, repeatability ≤0.1 nm; stray light ≤0.03 %T at 360 nm.
Display, control & data
- 10.1″ TFT colour capacitive touch screen on an ARM processing core: curve display, parameter setting and test-data import on the instrument.
- %T, Abs, C and E modes; photometric, quantitative, spectral scanning, kinetics and DNA/protein measurement.
- USB host / USB drive / RS232 / SD card data output.
- Built-in help menu; power-off protection keeps test data, spectra, regression equations and correction parameters for rapid re-initialisation.
Sample handling
- Standard 4×1 cm (4-position, 10 mm) cuvette holder fitted; automatic version optional.
- Chamber accepts micro to macro cells up to 100 mm optical path, with 4- or 8-position manual or automatic cell change (option).
- 5 cm or 10 cm cuvette holder, manual or automatic (option).
- Standard cuvette set: 2× quartz + 4× glass cuvettes.
Safety & utilities
- Automatic light-door technology — no black body needed, protects the photoelectric sensor.
- Wi-Fi xenon lamp control (option) — switch the lamp separately to extend its service life.
- Built-in thermal printer (option) for direct printout of results and data reports.
- Power supply AC 220 V ±10 %, 50/60 Hz, rated power 100 W; use a grounded outlet.
What distinguishes the three XENON-PMT models
All three models share the double-beam optics, the PMT detector, the 190–1100 nm range, the 10.1″ touch screen, the same photometric performance and the same data interfaces. XENON-PMT is the 2 nm bandwidth base configuration. XENON-PMTP narrows the fixed bandwidth to 1 nm and improves baseline flatness to ±0.0001 A. XENON-PMTS adds selectable 0.5 / 1 / 2 / 4 / 5 nm bandwidth with ±0.0001 A baseline flatness in a larger housing — see the model table.
