"As indicated in one of the articles in this issue, a very high degree of purity in the material used
for cathode ray tube screens is essential if good performance, and uniformity of colour within the standard tolerances is
to be maintained. Constant checks and critical tests on the screen material are conducted in the Mullard Material Research
Laboratory.
Our front cover shows a micro-analyst removing a small quantity of the screen material from a picture
tube which has already been processed, so that it may be submitted for analysis."
