Frames product of Polytetrafluoroethylene (PTFE) as chemically inert product with Proportions of 5cm×5cm were positioned over the surfaces to get sampled. Spiked surfaces were organized by adding spiking standard on to the product surfaces, and letting to dry at place temperature ahead of swabbing. Two swabs were being utilized subsequently. Purified h2o was employed as the solvent to wet the primary swab. The 2nd swab was utilized dry. A swab sample was geared up by wiping horizontally on one aspect from the swab, flipping the swab and wiping vertically on the other side with the swab. Every swab sample was then put inside of a examination tube.
