Estimate the optimal backflush time for your GC system by tracking % change in peak areas from previous runs. Start with an early backflush time and gradually increase; the time is optimized when the % change from previous run approaches zero.

Reference Formulas
Without a referenced peak:
\[ \text{%Change from Previous Run}= \frac{Target Peak Area_{n} – Target Peak Area_{n-1}}{Target Peak Area_{n−1}} \times 100 \]With a reference peak:
\[ \text{%Change from Previous Run}= \frac{\frac{Target Peak Area_{n}}{Reference Peak Area_{n}} – \frac{Target Peak Area_{n-1}}{Reference Peak Area_{n-1}}}{\frac{Target Peak Area_{n-1}}{Reference Peak Area_{n-1}}} \times 100 \]Before You Go
