Introduction

This document gives a method for the rapid determination of 22 elements in lubricating oil or base oil, and can quickly monitor the wear marks of used lubricating oil elephant: In addition, the document can cover a wide range of metal element types in base oils and recycled base oils: The additive elements in the unused lubricating oil are mainly derived from the compounding agent, if the concentration of the additive elements is different from their respective specifications Significant difference, indicating that the state of the lubricating oil is abnormal: Compared with the initial concentration data of the unused lubricating oil, the used lubricating oil Concentrations of wear metals can indicate abnormal wear, such as significant increases in boron, sodium, and potassium in lubricating oils, indicating that the contamination is due to equipment contamination: The result of a coolant leak in the equipment: Therefore this document is often used to monitor the operating status of machinery and determine when action is required Corrective Action: According to the concentration of metal elements in the recycled base oil, it can reflect the refining effect of the oil refining process: Application of this document to analyze metal content can Whether the base oil used in the reaction meets the specification requirements: Determination of various elements in lubricating oil and base oil inductively coupled plasma optical emission spectrometry Caution --- Personnel using this document should have practical experience in formal laboratory work: The use of this document may involve certain hazardous materials, equipment, and handling, this document does not address all possible safety issues: It is the user's responsibility to take appropriate safety and health measure:

1 Scope

This document describes the determination of used and unused lubricants and base oils by inductively coupled plasma optical emission spectrometry (ICP-AES): Additive elements, wear metals, and contaminants in base oils: This document applies to the determination of oil-soluble elements in lubricating oils, base oils and recycled base oils: The mass fraction of each element determined in this document See Table 1 for the number range and recommended wavelength: When the element content is not within the range shown in Table 1, the test process described in this document can still be used Determination, but the precision may not be applicable: This document does not apply to the quantitative analysis of samples containing insoluble particulates: Note: The analysis results are related to the particle size: If the particle size is larger than a few microns, the obtained results may be low: Table 1 Concentration ranges and recommended wavelengths of elements to be measured Element mass fraction range/(mg/kg) Wavelength/nm Aluminum 6~40 308:22,396:15,309:27 Barium 0:5~4 233:53,455:40,493:41 Boron 4~30 249:77 Calcium 40~9000 315:89, 317:93, 364:44, 422:67 Chromium 1~40 205:55,267:72 Copper 2~160 324:75 Iron 2~140 259:94,238:20 Lead 10~160 220:35 Magnesium 5~1700 279:08,279:55,285:21 Manganese 5~700 257:61,293:31,293:93 Molybdenum 5~200 202:03,281:62 Nickel 5~40 231:60,227:02,221:65 Phosphorus 10~1000 177:51, 178:29, 213:62, 214:91, 253:40 Potassium 40~1200 766:49 Sodium 7~70 589:59 Silicon 8~50 288:16,251:61 Silver 0:5~50 328:07 Sulfur 900~6000 180:73, 182:04, 182:62 ......
