Option Description
Sample- Sets the sampler to divide each sample between a selected number of bottles or put multiple
Based samples in one bottle.
Bottles per Sample (BPS)—Sets the sampler to divide a sample equally between a selected
number of bottles (e.g., when the sample volume is larger than the bottle volume). Refer to item

into each bottle (composite sampling). Refer to item 1 in
When 1 BPS and 1 SPB is selected, the sample is not divided. Each bottle holds one sample
(discrete sampling).
To collect identical sets of composite samples or a composite sample that is larger than the
capacity of a single bottle, enter a value that is more than one for BPS and SPB. For example,
when 2 BPS and 2 SPB are selected, the sampler puts the first sample in both Bottle 1 and Bottle
2. When the second sample is collected, the sampler puts the sample again in both Bottle 1 and
Bottle 2. When the third sample is collected, the sampler puts the sample into Bottle 3 and Bottle
4. Refer to item 3 in
Time- Sets the sampler to put the sample(s) that are collected during a time interval in each bottle.
Based Options: 5 minutes to 24 hours (default: 1 hour). Duration—Sets the time interval. First Bottle—
Sets the first bottle used in the sampling program.
Note: If the Program Start setting is a date and/or time in the past (e.g., yesterday at 08:00), the first sample is not
put in the first bottle selected. The sampler distributor goes forward one bottle for each time interval between the
programmed start time and the actual start time.
When it is necessary for the bottle numbers (positions) to identify the time (or day) the samples
they hold were collected, use time-based distribution (time-switched sampling). Refer to the
expanded user manual on the manufacturer's website to configure time-switched sampling.
