SampleSense FAST UHT

Mehlich-3-ICP is a method for determining bioavailable concentrations of 11 extractable micronutrient elements in soil samples. Mehlich-3-ICP is invaluable for determining the amount of fertilizer to apply to farm fields. Because soil analyses must be completed in a narrow time window, ultra-high sample throughtput with high-reliability is required.

SampleSense FAST UHT uses an inert injection valve with built-in optical sensors that automatically detect the liquid sample, inject the valve and trigger the ICP read in a tightly-timed analytical sequence. This ultra high-throughput system eliminates wasted time from the ICP method and can double or even triple sample throughput while recording missing or empty tubes.

Benefits:

  • 10 samples per minute Mehlich-3-ICP
  • Automatic sensing, injection, and triggering of the ICP analytical read
  • Detection and reporting of missing or empty sample tubes as “unsensed” samples
  • Adding SampleSense FAST UHT can double or even triple sample throughput
Ease of Use:
  • Optical detection of the filled sample loop automatically triggers ICP analysis
  • Removes timing and read delay adjustments
  • Eliminates method development when changing sample loop size for other methods

Automated Compensation of Physical Clogs and Timing Variables:

  • Reliable timing down to 0.05 s and better
  • Compensates for:
    - Partial clogs from filter paper fibers, particles, etc.
    - Accidental line kinks
    - Timing variables caused by high or low sample tube levels
    - ICP computer slow-down from software and data storage

Increased Productivity:

  • Produces long analytical runs without operator intervention
  • Minimized sample consumption allows reanalysis
  • Doubles or triples throughput of ICP instrument
  • Reduces argon consumption

SampleSense FAST UHT Rinse-out

The SampleSense FAST UHT rinse-out immediately reduces all elements to concentrations well below the bottom standard when using the six second Mehlich-3-ICP procedure. Additional seconds can be added to the rinse-out to meet lab requirements.

The system can deliver rinse-out factors of 1,000x, 10,000x or more depending on how clear the spray chamber needs to be before the next sample is introduced.
