Ionic Chromatography

Ion residue on metal surface can cause reliability issues, as a corrosion or short circuit. ALS Pathumthani provides services on most of ION contaminant for PCB/ PCBA, HDD and indoor air quality by ionic air sampling.

Our IC instrument is dedicated to the analysis of trace amounts (ppb) of anions such as Bromide, Chloride, Fluoride, Nitrate, Nitrite, Phosphate and Sulfate or cations such as Ammonium, Calcium, Lithium, Magnesium, Potassium and Sodium.

And as require by IPC (ipc.org), Weak Organic Acids (WOA) are also required for ensuring PCB/ PCBA product reliability.

Per IPC TM650 2.3.28, the concerned WOA are Acetate, Adipate, Formate, Glutamate, Malate, Methane Sulfonate, Succinate and Phthalate.

A gloved hand places a blue‑capped sample vial into an autosampler tray inside an ion chromatography laboratory instrument.

Some of the common applications include:

  • Determination of elemental composition of material or particles down to sub-micron level
  • Distribution of elemental composition of a material across a microscopic surface, and determination of corrosion or oxidation.
  • Measuring plating thickness
  • Inter-diffusion layers between metals
  • Explosive particles analysis
  • Abrasive particles analysis
