I. Instrument Applications

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a powerful analytical instrument for elemental analysis, characterized by minimal spectral lines, low interference, high analytical precision, fast analysis speed, and the ability to provide isotopic information. It can analyze all metallic elements in the periodic table, as well as most non-metallic elements such as As, Se, P, S, Si, and Te, with a detection limit below 1 ppb. The instrument is equipped with an autosampler.

II. Reservation Instructions

Samples can be submitted for testing, or users who have completed training may operate the instrument independently.

III. Sample Requirements

1. The instrument does not accept samples that are toxic, hazardous, radioactive, or contain hydrofluoric acid or organic substances.

2. Samples must be clear aqueous solutions (with a 2% HNO₃ matrix) and filtered through a syringe filter. No visible particulate matter is allowed in the sample.

3. ICP-MS measures concentrations at the ppb (μg/L) level, so sample concentrations must not be excessively high.

4. Each sample must have a minimum volume of 5 mL and be contained in a 10 mL capped centrifuge tube.
