Deuterium Lamp (Background Correction)

Specifications
Start Voltage: ≤350V
Background: The background strength near the main analysis line is lower than 1% of the analysis strength
Time for warm-up: <30min, usually from 5-15min
Stability: Baseline drift of copper lamp within 30min <1%, baseline drift of lamps of other elements within 5min <1%
Noise: <0.3%
Service life: Lamps with common elements ≥5000mA. H, lamps with fusible and volatile elements ≥3000mA. H
Maximum working current: From 10-20Ma

Advantage:
1. High Intensity: Karaltay lamps are specially designed to emit high intensity at the recommended operating current, resulting in low S/N ratio.
2. Low Operating Current: Our lamps may be operated at only half the instru¬ Ment manufacturer''s recommended current for sufficient intensity, resulting in long lifetime of the lamps.
3. Design: Our lamps are specially designed to meet or exceed requirements for various types of AAS, and to provide low detection limits for your most dif¬ Ficult analysis. We also manufacture Argon and/or Neon gas-filled lamps.
4. Quality Control: Karaltay utilizes Total Quality Control (TQC) to monitor, control and inspect every single step of the hollow cathode lamp manufac¬ Turing process. The materials are carefully selected in our manufacturing to avoid spectral interference from the fill gas or impurities in the cathode material.
5. Wide Selection: Single-element & multi-element lamps.

Beijing Karaltay Scientific Instrument Co., Ltd. is is a professional manufacturing company specializing in the production of laboratory equipment. Our main products include: Accessories for XRF (fusion system, grinding mill and press machine, chillers), Consumables for UV/VIS spectrophotometer and AAS (glass cells, quartz cells, hollow cathode lamps and graphite tubes) and Consumables for HPLC&GC (solvent filtration apparatus, syringe filter, syringe, membrane, gas generator and etc) and other laboratory equipment (electronic, shaking incubator, ice maker, freeze dryer and etc.) .

Ultra-low refrigerator;

The water chiller has provided for laboratory equipment, for instance XRD, XRF, AAS, ICP, ESCA, TEM, MRI, MBE, MOCVD, Electron probe, Laser, Vacuum Brazing Furnace, Oxygen/Nitrogen Analyzer, Thermal simulation tester, etc.

The YKKY series water chiller adopts the integrated structure; the unit includes: water circulation system, refrigeration system, and electric control system. The unit has used the high efficiency condenser, a slow-speed fan, in did not reduce the refrigeration quantity in the situation to reduce the system noise effectively. The electrical control has provided perfect system protection and the fault indicator function, further reduced unit’s failure rate, simultaneously has provided conveniently for the diagnosis.

The YKKY series water chiller has perfect protection. The breaker makes the short circuit protection. The compressor, the water pump, the fan have the overflow protection; the compressor has the overpressure protection. The water chiller will stop automatically when low-level water in tank, water temperature is too high or too low. The compressor will stop automatically when refrigeration system pressure is too high.
