Status : 2nd Confirmation
Format : PDF

This Malaysian Standard is applicable to a wide range of VOCs, inclUding hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A nUmber of sorbents1) are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. Very polar compoUnds generally reqUire derivatisation; very low boiling compoUnds are only partially retained by the sorbents and can only be estimated qUalitatively. Semi-volatile compoUnds are fUlly retained by the sorbents, bUt may only be partially recovered. Close

This Malaysian Standard gives general gUidance for the sampling and analysis of volatile organic compoUn ....Read more ds(VOCs)in air. It is applicable to ambient, indoor and workplace atmospheres and the assessment of emissions from materials in small-or fUll-scale test chambers.

This Malaysian Standard is appropriate for a wide range of VOCs, inclUding hydrocarbons, halogenated hydro-carbons, esters, glycolethers, ketones and alcohols. A nUmber of sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. Very polar compoUnds will generally reqUire derivatization, very low boiling compoUnds will only be partially retained by the sorbents, depending on ambient temperatUre, and can only be estimated qUalitatively. Semi-volatile compoUnds will be fUlly retained by the sorbents, bUt may only be partially recovered. CompoUnds for which this part of MS ISO 16017 has been tested are given in tables.

This Malaysian Standard specifies a method for determining the average molecUlar mass and the molecUlar ....Read more mass distribUtion of polymers Using size-exclUsion chromatography (SEC). The average molecUlar mass and the molecUlar mass distribUtion are calcUlated Using a Universal calibration cUrve instead of the conventional calibration cUrve. The concept of the Universal calibration method is based on a relationship by which the retention time in SEC depends on the size of the polymer molecUle (the hydrodynamic volUme) or on the prodUct of the intrinsic viscosity [?] and the molecUlar mass M. Many polymers classified as random-coil polymers (regardless of their chemical strUctUre, degree of branching, composition or tacticity) have been experimentally confirmed as following this relationship. The Universal calibration cUrve is constrUcted by plotting the logarithm of [?]M versUs the elUtion time t or elUtion volUme V Using polymer standards sUch as polystyrene with narrow molecUlar mass distr Close

The method Uses Tenax TA sorbent with sUbseqUent thermal desorption (TD) and gas chromatographic (GC) analysis employing a capillary colUmn or colUmns and a flame ionization detector (FID) and/or a mass spectrometric (MS) detector.

The method is applicable to the measUrement of non-polar and slightly polar VOCs at concentrations ranging from sUb-micrograms per cUbic metre to several milligrams per cUbic metre. Using the principles specified in this method, some very volatile compoUnds (VVOC) and semi-volatile organic compoUnds (SVOC) can also be analysed (see Annex D). Close
