Abstract
A method for sampling reaction products includes delivering a reactant through a sampling probe to contact a substance deposited on a substrate and reacting the reactant to form a reaction product. At least a portion of the reaction product is withdrawn through the sampling probe and analyzed. The sampling probe is contacted with the substrate during at least a portion of the delivering, reacting and withdrawing steps.
Claims7
A method for sampling reaction products, said method comprising the steps of:
- delivering a reactant through a sampling probe to contact a substance deposited on a substrate;
- allowing the reactant to react with the substance to form a reaction product;
- withdrawing at least a portion of the reaction product through the sampling probe;
- contacting the sampling probe with the substrate during at least a portion of the delivering, allowing and withdrawing steps so that a tip of the sampling probe may tilt to engage the substrate entirely around the substance;
- and
- analyzing, the withdrawn portion of the reaction product.
