If the height measurement was totally accountable for lack of precision at modest injection volumes, then any final results calculated utilizing peak spots under this line at any injection quantity need to display similar lack of precision. Correspondingly, for indoxacarb, the same loss of precision would've been witnessed at each of the chosen injection volumes. Indoxacarb wasn't in line with this speculation. The loss of precision is just not entirely explained by absolutely the size of the peak.
