Example: "In the study, analysis samples were collected from various locations to ensure a comprehensive evaluation of the data."
Alternatives: "samples for analysis were gathered" or "samples intended for analysis were obtained."
For microbial analysis, samples were collected in 250 mL glass bottles.
For FACS analysis, samples were collected by centrifugation, washed with 1X phosphate buffer saline, and re-suspended in 1X PBS to ca 106 CFU/ml prior to being run in a FACS Calibur flow cytometer (BD Biosiences, CA).
For the qPCR analysis samples were collected at 8, 24, 32, 48, 72, and 96 hai.
For data analysis, samples were collected at different time points (the lag, early exponential, late exponential and stationary growth phases).
For seasonal expression analysis, samples were collected from autumn to late spring at monthly intervals from A. chinensis 'Hort16A' and A. deliciosa 'Hayward' vines growing in the research orchard near Te Puke, New Zealand, during the season of 2006-2007.
For PD (ANC) analysis, samples were collected at −1 h on days 1 4 and at −1, 0.5, 1, 2, 4, 6, 8, 24, 48, 72, 96, and 120 h following dose administration on day 5.

For spatial analysis, soil samples were collected from 30 different locations, belonging to 6 distinct land uses dominant in the megacity.
For in situ measurement and laboratory analysis, water samples were collected from three different depths (surface, middle, and 0.5 m above the bottom) of the study points under three distinct seasons.
For in-situ measurement and laboratory analysis, water samples were collected from the three discrete layers of the selected measuring stations during post-monsoon, winter and monsoon seasons under both high and low tide conditions.
For S100B analysis, blood samples were collected and immediately centrifuged at 1,200×g for 10 min, and the supernatant serum was stored at −80°C.
