A 33-element calibration kit for ICP-OES analysis of oils
The Inorganic Ventures 2 Standard ASOS Kit, 5 ppm, is a multi-element calibration standard for ICP-OES (inductively coupled plasma optical emission spectroscopy) analysis of oils. Each kit contains two 500 mL solutions that together cover 33 elements at 5 µg/g (5 ppm). The elements are split across two solutions to optimize compatibility, stability and interference reduction. After a 10x dilution with ASOSolv solvent, the kit gives a calibration level of 0.5 µg/g.
The kits are designed for use with ASOSolv, a hybrid organic solvent that bridges oil-based sample matrices and aqueous certified reference materials. It supports calibration for wear metals, additive metals, contaminant testing and edible oil analysis using direct dilution workflows.
Key features
- 33 elements in two solutions: 18 elements in a 10% HNO3 solution and 15 elements in a 20% HCl / HF solution, so each element sits in a compatible matrix.
- Two 500 mL bottles per kit: A nitric acid solution and a hydrochloric acid solution, supplied together.
- Built for direct dilution: Dilute 10x with ASOSolv to prepare calibration standards for oil analysis.
- Aqueous-based standards: Calibrating with aqueous certified reference materials helps reduce the sulfur background that traditional organometallic oil standards can contribute.
- Includes sulfur: Sulfur is one of the 33 elements in the kit.
- Accredited producer: Produced by Inorganic Ventures, an ISO 17034 and ISO/IEC 17025 accredited manufacturer, with a Certificate of Analysis provided for every lot.
Ideal for
- Wear metals and additive elements in lubricating oils
- Edible oil and industrial oil analysis
- Laboratories that want to calibrate for oil analysis using aqueous standards
- Methods Inorganic Ventures lists as aligned with ASOSolv workflows: ASTM D5185, ASTM D4951, ASTM D5708, ISO 21033, ISO 10540-3 and FDA EAM 4.4
Choosing the right kit
The kits are sold by concentration. The calibration level you get after the 10x dilution with ASOSolv is one tenth of the concentration of each solution. Check the part number carefully when ordering. You will also need ASOSolv solvent: see the ASOSolv Solvent Blank.
| Kit | Concentration of each solution | Calibration level after 10x dilution with ASOSolv |
|---|---|---|
| ASOS-1-CAL-1PPM | 1 ppm | 0.1 µg/g |
| ASOS-1-CAL-2.5PPM | 2.5 ppm | 0.25 µg/g |
| ASOS-1-CAL-5PPM (this kit) | 5 ppm | 0.5 µg/g |
| ASOS-1-CAL-10PPM | 10 ppm | 1 µg/g |
| ASOS-1-CAL-50PPM | 50 ppm | 5 µg/g |
| ASOS-1-CAL-100PPM | 100 ppm | 10 µg/g |
| ASOS-1-CAL-200PPM | 200 ppm | 20 µg/g |
| ASOS-1-CAL-500PPM | 500 ppm | 50 µg/g |
| ASOS-1-CAL-BLANK | Blank (0 ppm) | 0 µg/g (blank) |
