Five ions can be determ<strong>in</strong>ed simultaneously, namely bromide, chloride, nitrate,<br />
phosphate and sulfate.<br />
Analytical results are expressed as hydrobromic, hydrochloric, nitric, phosphoric<br />
and sulfuric acid.<br />
Samples are stable <strong>for</strong> 21 days at 25°C.<br />
All <strong>the</strong> nitrate ions not orig<strong>in</strong>at<strong>in</strong>g from <strong>the</strong> acid can cause positive <strong>in</strong>terference.
