Nd:YAG Laser Ablation system

The new UP266 MACRO, a large beam, 266nm UV Nd:YAG laser ablation system is designed to boost ICP-OES and ICP-MS sensitivity well beyond the abilities of all other 266 laser ablation systems.

The UP266 MACRO produces flat craters ranging from 30µm to 750µm in diameter through precision, aperture imaging. This system also features VERI™, (Vernier Extended Range Increments) functionality that extends these aperture imaged flat spot sizes from 20µm to greater than1100µm.

The UP266 MACRO is value engineered to provide the best performance at an affordable price

Features

Flat, pre-calibrated spots from 30µm spots and
      up to > 750µm.
VERITM functionality for spots from 20µm to
      >1200µm.
ICP-OES detection limits of < 1µg/g (1ppm),
      are possible.
ICP-MS detection limits of < 1ng/g (1ppb),
      are possible.
>15J/cm² energy density. Enough to efficiently
      ablate glass, steel, noble metals, plastics,
      ceramics and biological matrices.
Automated energy control via an optical attenuator
      for maximum dynamic range and stability.
Closed-loop control with all makes of ICP-OES
      and ICP-MS instruments.
Color sample viewing with a wide FOV (field-of-view).
Sample Map Navigation for up to 50mm virtual FOV
      of the sample.

Applications

Bulk and inclusion analysis of metals
Forensic analysis of plastics, ceramics,
paints, glass
Biological tissues, tree rings and gels
Sulfate, Sulfite analysis
Environmental air filters, wear metals,
soils analysis

UP266MACRO system software operates under all Windows platforms (’98, NT, 2000, XP). Integrated control of sample analyses is a standard design consideration.
