model) and 2 different columns (same stationary phase and manufacturer, but different lot) by 2
different analysts.

System suitability
:
Calibration solutions of maltotriose (0.005 nmol/mL – 0.9 nmol/mL) at 11 different levels, were
prepared in triplicate all containing the laminaritriose internal standard (at 0.304 nmol/mL)
Recommendation:
The method tested has can determine the GOS content of most infant formula and adult
nutritional products within the concentrations typically used in such products.
The method is a significant improvement over current solutions for the determination of GOS in
lactose‐containing products.
I recommend to move this method to First Action.
