SAMPLE CHANGERS FOR AUTOMATED GAMMA SPECTROCOPY

All Gamma Products sample changer systems include: Standard Microsoft Windows operations and G3000W operating software, all systems (48 states) are installed and include a 1 year on-site warranty.

G4000 Planchet Sample Changer

  • This system is a combination of the proven reliable G5000-50T and -100T Tower system elevator mechanism in our alpha/beta counting systems and the steel shield is from our popular G3000 Marinelli sample changer system
  • The system is available with either a Short Narrow or Wide Tower or a Tall Narrow or Wide Tower.
  • The Short Towers hold 2 each 25 sample cartridges, the Wide Towers hold 5 each 20 sample cartridges
  • The Narrow Towers accomdate sample diameters of 2" and the Wide Towers accomodate up to 5" in diameter

Applications for G4000 Planchet Sample Changer

  • Ideally suited for Ra226/228 EPA drinking water analysis by gamma spectroscopy
  • Equally suited for Ra226/228 in soil samples with large/flat cans
  • Appropriate for Ra226/228 EPA "coal ash run off" waters
  • and any gamma spec "hockey puck" samples

G3000M Series Marinelli Sample Changer

  • Accommodates 1/4, 1/2, 1, 2, or 4 liter Marinelli beakers
  • 12 position turntable
  • Handles beakers from the bottom, eliminates gripping and dropping problems
  • Stepping motor driven turntable, slide, and sample elevator
  • Low background shield - lead or steel
  • PC based motor drive controller
  • Automatic door option (to achieve near 4 pi shielding, except for detector entry) available only at time of the initial system purchase.
  • Accomodates nearly all HPGE detectors and cooling options

G3000C Series Container Sample Changer

  • Accommodates up to 20 each 4" samples or 24 each 3-1/4" samples. Smaller diameter samples can allow more samples on the turntable
  • Typically 16 X 16 X 16" ID but can be larger
  • Low background shield: lead or steel
  • PC based motor drive controller
  • Automatic door option (to achieve near 4 pi shielding, except for detector entry) available only at the time of initial system purchase.
  • Accomodates nearly all HPGE detectors and cooling options
  • Essentially the same as the Marinelli system but without the elevator to lower the sample over the detector

Integrated Door Option For G3000/G4000 Sample Changers

Must be ordered at the same time the changer system is ordered. Not a field upgrade.

CUSTOM SYSTEMS DO NOT SCARE US

Actually, we like it! We have a variety of detectors, sample holders, sample loaders, and shielding options that we can configure to meet your specific needs. You have chosen your procedures and the sample prep supplies you want to use. We don't want to change what you do, we just want to automate it. Call us to discuss your specific requirements.

GAMMA PRODUCTS QUEUE BUILDER PROGRAM FOR ALL G3000 & G4000 SYSTEMS

For automating systems with either Gamma Vision or Genie Software. Queue Builder runs either job or script files for each sample in the batch.
