Título Organic isocyanates in air - Laboratory method using 1-(2-methoxyphenyl) piperazine solution and high performance liquid chromatography
Información bibliográfica Health and Safety Executive Sales Point, St. Hugh's House, Stanley Precinct, Bootle, Merseyside L20 3QY, United Kingdom, Mar. 1983. 5p. Illus. 12 ref. Price: £1.00.
Resumen Contents of this guidance note: Properties, uses, toxicity and first aid in case of massive exposure to organic isocyanates; determination method (sampling through a glass impinger containing the absorbing solution of 1-(2-methoxyphenyl) piperazine; the organic isocyanates react to form urea derivatives; the resulting solution is concentrated and analysed with a high performance liquid chromatograph equipped with an ultraviolet and an electrochemical detector; the total isocyanate concentration is calculated from the sum of all isocyanate-derived chromatograph peaks). Scope: suitable for measurement over periods in the range of 10min to 8h, both for personal and area sampling. Analytical range: 7-140µg NC0/m3 for 10l air samples. Precision: 10%. Aromatic amines and the presence of several isocyanate types will provide interference.
