Installation
3.7 Gas-sensitive electrode
Important Note: Before using the AMTAX sc for the first time, the
electrode has to be filled with the supplied electrolyte, see
section 3.7.1.1 .
The ammonium in the sample is converted into (dissolved)
ammonia gas by adding sodium hydroxide solution. This dissolved
ammonia gas content will be converted into a measurable pH shift
in the electrode.
3.7.1 Installation of the electrode and electrolyte
The electrode body and the glass electrode are sold as a unit
(Refer to
section 8.4, page 66 ). Use the electrode only in the
supplied enclosure. To prevent inaccurate readings or instrument
malfunction, do not use a different enclosure than that supplied by
the manufacturer.
3.7.1.1 Fill the electrode with electrolyte
CAUTION
Review all SDS/MSDS information and use recommended
safety measures to prevent exposure to potential chemical
hazards.
Important Note: Never lubricate the membrane cap or the
electrode with grease, silicone oil or Vaseline. This will cause
damage to the Teflon membrane which will cause poor
performance.
Pre-requisites:
• The items required to fill the electrode are located in the bag
attached to the base of the enclosure.
• Before the electrolyte can be added to the electrode, open the
instrument enclosure and disconnect the electrode cable from
the analyzer panel.
