AA LAMPS Hollow Cathode Lamps HCL Lamps Elemental Lamps

NEW

We are able to supply more than 70 different hallow cathode lamps of both 37mm (1.5") and 50mm (2") diameter, a variety Deuterium lamps and High Intensity Hallow Cathode Lamps for use with most available spectrometers.

High Intensity HCLs
Aurora's unique High Intensity Hollow Cathode Lamps (HIHCLs) overcome the fundamental limitations of standard hollow cathode lamps. In these lamps a secondary discharge is struck between an efficient electron emitter and the anode. The secondary discharge ensures that the majority of the atoms at the face of the cathode are excited and that very few atoms remain in the ground state. This eliminates self-absorption effects and improves both the sensitivity and linearity during analysis.

Furthermore, the line width of these HIHCLs is narrower than those of standard lamps, even at higher current. As a result improved signal to noise ratios are observed.

These lamps are compatible with Super Lamp Systems.

Quality
Each HCL is individually tested in our laboratory to ensure its quality and stability. All lamps available from Aurora Biomed feature:

High purity cathode and fill gases
Narrow bandwidths
Unmatched lifetimes
High stability
Low Noise

 

 

Hollow Cathode Lamps 

 

Varsal designs and manufactures a complete line of hollow cathode lamps to meet the strictest standards of most atomic absorption spectrometer instruments. We manufacture lamps of different sizes and with argon and/or neon gas fills to assure optimum results on a wide variety of instruments. Our technical ability to produce hollow cathode lamps that meet the demanding specifications of instrument manufacturers is only surpassed by the company's customer service and on-time delivery responsiveness.

 

Varsal Advantages

 

  • Long life for economical, operator convenience
  • High intensity light output resulting in low signal-to-noise ratio and excellent performance
  • Low operating current to extend lifetime of lamps even further
  • Enhanced sensitivity to produce great results even with difficult samples
  • Wide selection so Varsal can be your one source for all HCL's
  • Reliable quality so your expectations will always be met

 

High Intensity 
Our lamps are specially designed to emit high intensity at the recommended operating current, resulting in low Signal-to-Noise ratio and excellent performance.

 

Low Operating Current 
Our lamps may be operated at only half of the instrument manufacturer's recommended current for sufficient intensity, resulting in long lifetime of the lamps. 

 

Category Data
Glowing starting voltage: 300 V
Radiation stability: 1% over 30 minutes
Size: 2" for Perkin-Elmer Diameter: 50 mm, Length: 180 mm
Size: 1.5" lamps Diameter: 38 mm, Length: 160 mm

 

 

 

Quality Control 
Varsal utilizes Total Quality Control (TQC) to monitor, control and inspect every single step of the hollow cathode lamp manufacturing process. The materials are carefully selected in our manufacturing to avoid spectral interference from fill gas or impurities in the cathode material.

 

Every lamp is thoroughly tested prior to shipment. Under same testing conditions, the radiation intensity of every lamp is equal to or better than those made by other vendors.

 

Warranty
All hollow cathode lamps are warranted for a standard 2-year limited warranty. Each regular element lamp carries a 5000 mA-Hour warranty (such as Cu, Ni, Ca, MG, etc). Each volatile element lamp carries a 3000 mA-Hour warranty (such as As, Se, Sb, Bi, Pb, Cd, etc). Varsal will replace any lamp that does not perform to its specification during this period assuming the lamp was properly used.

 

Want to Extend the Life of Your Lamps?
The JH-B HCL Activator detailed below is a power supply designed to pre-warm a HCL prior to use, enhance the durability of the lamp and improve signal emission. Use the JH-B HCL Activator to ¡°supercharge¡± your lamps.

 

List of Atomic Absorption Spectrometers Manufacturers 
Varsals HCL can be used on Atomic Absorption Spectrometers manufactured by:

 

  • Perkin-Elmer
  • Varian
  • BUCK Scientific
  • GBC
  • Hitachi
  • Shimadzu
  • Thermal Jarrel Ash
  • IL
  • Unicom
  • LEEMAN Labs
  • Phillips

 

hollow cathode lamp 1.5 inch1.5" Hollow Cathode Lamp 

 

  • Regular 1.5" lamps for all systems except Perkin-Elmer system.
  • Self-reversal 1.5" lamps for Shimadzu, Thermal Jarrel Ash, LEEMAN Labs whose AAS system requires self-reversal background correction abilities.
  • Even though Varian systems do not require self-reversal lamps, they are suggested and recommended because of longer life time and higher intensity.

 

hollow cathode lamp 2 inch 2" Hollow Cathode Lamp 

 

  • Uncoded (regular) 2" lamps can be used for all Perkin-Elmer atomic absorption spectrometers. Some models do require different conversion cables.
  • Some models use a 9 - pin connector while the AAnalyst Series use a 4-pin connector as pictured below. Please select the right lamp as pictured below for your instrument.
