Get IDENTIFICATION AND CHEMICAL

Four steps to successful substance identification Analyse your substance. Firstly, you need to decide whether or not you already have the necessary analytical data to identify your substance for REACH purposes. ... Detail the composition of your substance. ... Name the substance. ... Assign a numerical identifier.

To identify if a substance is hazardous, check the product's container label and/or the SDS which is available from the supplier. If a product is not classified as a hazardous chemical under the Work Health and Safety Act 2011, a SDS is not required and therefore may not be available.

The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes.

The mass spectrometer (MS) identifies and quantifies the chemicals.

Chemical identification is defined as assigning an analyte to one from known chemical compounds or a group/class of compounds. General principles for identification through the use of chemical tests and instrumental measurements are formulated.

Typically, the identity of a substance can be described by a: chemical name, for example, benzene; number, for example, EC number 200-753-7, and. chemical composition, for example, >99 % benzene and <1 % . The composition is determined by chemical analysis.

The first and most essential step leading to safe use of chemicals is to know their identity, to their hazards to health and the environment and the means to control them.

Reading chemical labels and Safety Data Sheets (SDSs) The product labels contain clear symbols that quickly identify the chemical as hazardous. These may include: Pictograms - recognisable symbols that identify hazards (eg, flames, bomb, skull and crossbones) Signal words - WARNING or DANGER.
