represents a selective, rapid, accurate and favorably
priced method, which is described in this Bulletin.
Examples are used to show how determinations can
be carried out with the 692 pH/Ion Meter using either
direct measurement or the standard addition technique.
The sodium concentration has been determined
in standard solutions, water samples (tap water, mineral
water, waste water), foodstuffs (spinach, baby
food) and urine.
The construction, working principles and areas of application
of the two Metrohm ion-selective sodium
electrodes – the 6.0501.100 glass membrane ISE and
the 6.0508.100 polymer membrane ISE – are explained
in detail.详细>
