THE PROCESS

DIGEST → IONIZE → COUNT
STEP 01

MICROWAVE DIGESTION

CEM MARS 6 closed-vessel nitric-acid ramp to 200 °C — a 45-minute cycle breaks any matrix down to clear atomic liquid.

STEP 02

DILUTE & SPIKE

18.2 MΩ·cm ultra-pure dilution; a Rh/In/Bi internal-standard blend tracks and corrects instrument drift in real time.

STEP 03

OVERNIGHT QUEUE

SPS 4 autosampler racks run unattended — calibration line, samples, then a wash between every vial to kill carryover.

STEP 04

10,000 K PLASMA

The argon torch atomizes and ionizes every element; the ORS4 helium collision cell strips spectral interferences.

STEP 05

DETECTION & CoA

Quadrupole mass filter + dual-mode electron multiplier count the ions; MassHunter exports the Certificate of Analysis.
