Analytical Procedure
The procedure, SMV (PC) 3201859-01V, for determining the content of Isotridecyl 3,5,5Trimethylhexanoate in double-distilled water was developed in this study. The method used was Gas chromatography (GC) with flame ionisation detection (FID). A summary of the analytical procedure is shown in Appendix 2.
The method was assessed against the criteria detailed in the following sections:
Specificity
Blank solutions were prepared and run with the rest of the validation samples, to assess freedom from any interfering (co-chromatographic) peaks.
Sensitivity
The limit of quantification (LOQ) was described as the lowest fortification level where acceptable precision and accuracy data were obtained.
Linearity
The analytical calibration covered a range appropriate for the anticipated concentration of Isotridecyl 3,5,5-Trimethylhexanoate in double-distilled water. The linearity of detector response for standard solutions over the concentration range (minimum of five different concentrations) was determined by least squares linear regression with a 1/x weighting.
Accuracy and Precision (Repeatability)
For procedure SMV (PC) 3201859-01V, the accuracy and precision of the analysis was determined by analysis of five replicates of prepared sample solutions. The sample solutions were prepared at the following concentrations 1, 10 and 100 µg/mL by spiking into double-distilled water from a stock solution of Isotridecyl 3,5,5-Trimethylhexanoate in acetone. The solutions were super saturated with sodium chloride (0.4 g/mL) and then extracted with hexane, centrifuged a speed setting of 2500 rpm for 5 minutes and the hexane layer analysed. The volume of hexane chosen was such that the concentration was within the calibration line.
Acceptance criteria (SANCO/3029/99 rev. 4.) Accuracy (recovery)
The mean recovery values should be within 70 to 110% (ideally with the mean in the range 80 to 100%).
A suitable test for outliers may be applied to the accuracy data, for example the Grubbs or Dixons Tests.
Precision (repeatability)
The precision percent relative standard deviation (%RSD) should be ≤ 20%. - Key result
