ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) is a core instrument widely used for precise multi-element analysis in industries such as chemicals, food, and pharmaceuticals. During sample preparation, instrument operation, and routine maintenance, frequent use of various chemical reagents is required, which may pose occupational health risks to operators.
Risks Associated with ICP-OES Sample Pretreatment
In physical and chemical experiments involved in sample pretreatment inorganic acids are frequently used, with nitric acid and hydrochloric acid being the most common. These are primarily used for the digestion of various solid and liquid samples to completely break down the sample matrix and release the elements to be analyzed. Such acidic reagents are highly volatile; prolonged inhalation may cause respiratory tract damage and eye irritation. They are also highly corrosive, posing a risk of chemical burns upon skin contact.
Risks Associated with ICP-OES Instrument Maintenance
Safety hazards during instrument maintenance must also not be overlooked. When disassembling components such as the sample pump tubing and the atomizer during routine maintenance, residual sample solutions may evaporate, and there is even a risk of minor sample splashes. Furthermore, when cleaning components such as the atomizer, central tube, and rectangular tube, a mixed acid solution prepared from analytically pure nitric acid and hydrochloric acid is typically used to ensure thorough cleaning. During the preparation of the mixed acid solution and the cleaning of components, acid fumes and irritating odors are generated. Inhalation of these substances may irritate the respiratory tract and eyes, posing a potential health hazard to laboratory personnel.
