Infant formula and adult nutritionals — Determination of trans and total (cis + trans) vitamin K1 co...
This document specifies a method for the quantitative determination of trans and total (cis + trans) vitamin K1 in infant, pediatric and adult nutritionals using normal phase (NP) high-performance liquid chromatography (HPLC) with post-column reduction and fluorescence detection. The method demonstrated good linearity over a standard range of ~2 μg/l to 80 μg/l trans vitamin K1, and the limit of…
Leather — Chemical determination of formaldehyde content — Part 1: Method using high performance liq...
This document specifies a method for the determination of free and released formaldehyde in leathers. This method, based on high performance liquid chromatography (HPLC), is selective and not sensitive to coloured extracts and is intended to be used for precise quantification of formaldehyde.
The formaldehyde content is taken to be the quantity of free-formaldehyde and formaldehyde extracted…
Leather — Chemical determination of formaldehyde content — Part 2: Method using colorimetric analysi...
This document specifies a method for the determination of free and released formaldehyde in leathers. This method, based on colorimetric analysis, is not intended to be used for a precise quantification of formaldehyde.
The formaldehyde content is taken to be the quantity of free-formaldehyde and formaldehyde extracted through hydrolysis contained in a water extract from the leather under…
Leather — Chemical determination of chromic oxide content — Part 4: Quantification by inductively co...
This document describes a method for the determination of chromium in aqueous solution obtained from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state.
This method describes the determination of chromium by inductively coupled plasma (ICP) and is applicable to leathers which are expected to have chromic oxide contents in…
