Question

Not sure if anyone can answer this because it's from a lab, but I'll provide as much info as I can.

These following sets of numbers are important in this question- They are retention time and peak intensity

1 - 5.0 sec, 1556 counts

2 - 12.5 sec, 2073 counts

3- 18.3 sec , 1279 counts

4- 29.7 sec, 705 counts

5- 35.0 sec, 707 counts

6- 52.5 sec, 396 counts

Ok, now for the follwing question, the peak intensity and retention times of the peaks above need to be looked at. For this question, the standard solution was diluted in half, so all of the peak intensities should be reduced by about half. Compare peak intensities observed in the numbers above, to the intensities of the peaks from running the diluted standards in the following question.. The peaks which were not reduced by half, are the solvent peaks and you should input the retention times for these solvent peaks for the answer to this question.

For this experiment, I had to dilute the sample by 50% by adding 1.0 mL of solvent solution. After all of those steps were done, it would show several peaks on the monitor, and several of them were reduced by 50% in the diluted sample. However, other peaks werent much different and that's because of the compounds present in the solvent solution, rather than in the drug standards.

What are the retention time for the two peaks, that can be assigned by this method to the solvent solution, rather than to te drug standards?

First solvent peak - ? s

Second solvent peak - ? s
