analysis of high-purity zinc and zinc alloys - what is die casting

The physical methods of analysis, such as the use of polarizers or spectrometer, are particularly suitable for the determination of trace impurities in zinc and its alloys.
In 1941, a panel was appointed by NGOs
The black Industry Commission of the British standard body considered the recommended method for spectrum and spectral analysis of high purity zinc and zinc alloys for die casting.
In its review of early work, the panel found that, despite the use of camcorders in certain laboratories, neither the details nor the precision of the technology were sufficiently defined, it is not possible to justify the immediate recommendation of the spectral method;
It was observed that the use of the polar spectrometer was not even so developed.
As a result, the group planned and conducted a lot of experimental work by some interested organizations.
The description of these studies has been published under the heading "extreme spectrum and spectral analysis of high purity zinc and zinc alloys for die casting (H. M.
1945) office of stationery.
Based on this work, the suggested methodology has been prepared so that comparative information can be collected.
The panel's recommendation, "recommended method for the spectrum and spectral analysis of high purity zinc and zinc alloys for die casting "(
UK standard 12251945. Pp. 36. 2s. net)
, Designed to be a guide, not a strict binding specification.
These methods are effective, however, as their field of analytical chemistry is rapidly expanding, the Commission does not want to hinder development with strict rules.
It is therefore intended to review the position as early as possible based on further experience gained using these methods.
