After collection of these samples , analysis is with through emission spediometry or flame atomic absorptionDetection of very(prenominal) metals can be through minute or pose quantitiesTetramethyl and Tetraethyl compounds of lead can be analysed utilise In-House method as the stop gap procedureAdvances in techniques and different levels of exposure limits whitethorn render a given OSHA method inapplicableThe first upon in analysis is to make bunk particles lesser i .e grinding , or crushing to powder form . The samples be mixed with strong acid concentrates or if possible using de ionised water . The sample solution is then give way , and exposed to atomic absorption or spectrophotometer raysThrough the measure of diagnostic wavelength , it is possible to determine the element but after atomisation and achievement of the excited stage of the atomsSamples may be from the press cutting surface like the arms , haves or get it on . A wise packet is torn break without mournful the wire and given to the worker being evaluated . Employee is to omit the cover from the package and unfold it .
