ICP-OES Testing Service, ICP-OES Analytical Service

Overview

ICP-OES Testing Service and ICP-OES Analytical Service offer fast, accurate and reliable analysis of elements in a sample. This high-precision analytical service utilizes the latest ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry) technology to detect a range of metals and non-metals at parts-per-million, parts-per-billion or trace levels. Results are provided quickly and with a high degree of accuracy.

Sample requirements

Pre-treated Solution Samples:

• a. Transparent and Clear Solution: The solution must be stable with no precipitate. For colored solutions, confirm whether they are ionic solutions; if unsure, perform acid treatment before analysis to avoid damaging the instrument. Provide 5-10 ml of sample, preferably neutral to slightly acidic, with an acid concentration below 5%. Solutions containing hydrofluoric acid (HF) cannot be tested directly—ensure F ions are fully evaporated, and pre-digested samples must be diluted.
• b. Organic Solutions: Carbon-containing solutions cannot be tested directly and must be digested with nitric acid to eliminate carbon.
• c. Free of Impurities: Samples must not contain any insoluble impurities or organic matter. It is recommended to filter the solution through a 0.45 μm membrane. Secure the container lid tightly and seal it with parafilm to prevent leakage.

Untreated Liquid Samples:

• a. Routine Water Samples: Provide at least 50 ml. For custom or other liquid samples, provide at least 10 ml and label the sample composition to aid in selecting the appropriate digestion method.
• b. Secure the container: Ensure the container lid is tightly closed and sealed with parafilm to prevent leakage.

Untreated Solid Samples:

• a. Powder Samples: Provide at least 100 mg of sample, pre-ground into a fine powder if possible, and sieved through a 200-mesh sieve if conditions allow. For microwave digestion, provide at least 200 mg.
• b. Limited Quantity Samples: Wrap small quantities of solid samples in weighing paper and place them in a tube.

Recovery Notice:
This is a destructive testing method. Samples used during analysis cannot be recovered, and only any remaining sample (if available) can be returned.

Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)

Inductively Coupled Plasma (ICP) based analytical techniques can provide quantitative bulk elemental composition of a wide variety of sample types, including powders, solids, liquids, and suspensions. Solid samples are generally dissolved or digested using a combination of acids in a closed microwave system, thus retaining potentially volatile analyte species. The resulting sample solution is then nebulized into the core of an inductively coupled argon plasma, where temperatures of approximately 9000 K are attained. At such high temperatures, the nebulized solution is vaporized, and the analyte species are atomized, ionized and thermally excited. The analyte species can then be detected and quantified with an optical emission spectrometer (OES), which measures the intensity of radiation emitted at the element-specific, characteristic wavelength from thermally excited analyte atoms or ions. Intensity measurements are converted to elemental concentration by comparison with calibration standards. This technique is especially powerful for quantitative chemical analysis when standards are not available.
