more than one determinative analysis run<br />

is required to cover all analytes <strong>of</strong> interest<br />

w ith sufficient selectivity and sensitivity…<br />

<strong>The</strong> broader the spectrum <strong>of</strong> analytes covered by the MRM,<br />

<strong>The</strong> less additional methods are required to cover all analytes<br />

<strong>The</strong> more efficient and economical the analysis<br />
