Upon opening of the bottles, samples to measure the dissolved 15N2 were taken and stored in gas-tight glass vials (Exetainer®) until analysis.
In all of these studies ambient air was sampled at 0.5 to 1 m above ground surface, at or above the height of the opening of our sampling containers (˜0.4 m).
An arrangement was made in this quartz tube for the gas inlet, opening of the evaporation source, sample holder, and the gas outlet.
It involves the design of the device structure of the dual-tube sampling, the process of opening and closing the sampling hole, and some key technical parameters.
Air gas was used as the main plasma gas (5 L/min).The applied voltage was 15 kV, and the distance between the opening of the plasma nozzle and the samples was 1 cm for all cases of plasma treatment.
Routinely, a swab (eSwab™, BD, Heidelberg, Germany) is taken from the interenteric fluid immediately after opening of the peritoneal cavity; further samples may be obtained from suspect sites at the discretion of the surgeon.
Upon opening of the bags in the laboratory, samples of the dog food were analyzed for Salmonella and aerobic plate counts using the methods described below in conjunction with the standard cultural and confirmatory techniques from the FDA Bacteriological Analytical Manual were used to screen for Salmonella (Andrews et al. 2016).
We then sealed the other opening of the capillary with odorless gum to suspend the sample aliquot inside the capillary, 1 cm away from the sample-containing end.
The sample run began with the opening of the entrance door.
As Figure 1 illustrates, during the day, this temperature could be achieved within 15 min and remained fairly constant with a slight drop during sampling due to the opening of the chamber.
