number of samples. This allows you to control the number of
samples in each bottle. When you switch bottles or sets on a time
basis, the total volume of each bottle or bottle set may vary in
samples-per-bottle multiplexing.
3.3.3 Multiple-Bottle
Compositing
The extended programming mode offers a third multiplexing pos-
sibility: multiple-bottle compositing. Multiple-bottle compositing
combines samples-per-bottle and bottles-per-sample multi-
plexing by depositing multiple samples in a bottle set. At each
sample event, the sampler places a sample into each bottle of a
set. This is repeated until each bottle of the set contains a pro-
grammed number of samples. Figure
3-4 illustrates multiple
bottle compositing. You can switch the bottle sets after a pro-
grammed number of samples have been deposited or after a pro-
grammed period of time elapses. Multiple-bottle compositing is
useful when you want a series of identical sets of samples or a
larger volume composite sample than you can collect in one
bottle. You can use multiple-bottle compositing with time-paced
or flow-paced routines.
3.3.4 Stops and Resumes The Sampling Stops and Resumes feature, available in the
extended programming mode, allows you to create an inter-
mittent sampling schedule. You can program the sampler to stop
the routine at a specific time, and then resume the routine later.
You can enter as many as 12 stop times and 12 resume times.
Stops and resumes can be used with time-paced and flow-paced
routines and with routines programmed for nonuniform time
intervals.

3.4 Stormwater Sampling
The 3700 Sampler’s STORM programming lets you meet storm-
water monitoring requirements easily. The 3700 Portable’s
STORM pacing program divides the bottles of the 2-, 4-, 8-, and
24-bottle configurations into two separate groups. The first group
receives a first flush (time-paced) grab sample. The second bottle
group receives either a flow-paced or time-paced “composite”
sample. The 3700 Compact’s 24-bottle configuration can also be
used for STORM programming.
