Second Bottle Group

How to allocate bottles to the bottle groups – Use the next
three displays to determine the both the sample distribution and
the number of bottles allocated to the bottle groups.

A bottle group can contain one or more bottles. You can allocate
all bottles but one to the first bottle group. The STORM routine
will automatically allocate the remaining bottles (or bottle) to the
second bottle group. (It obtains the total number of bottles from
the bottle number setting in the bottles and sizes configure
option.) Refer to the displays above; a 24-bottle sampler pro-
grammed to distribute samples to three bottles at two sample
events would allocate six bottles to the first bottle group. The
remaining 18 bottles to the second bottle group.
Sample distribution and sample volumes for the first and
second bottle groups – STORM sampling supports sequential
s a m p l i n g a s w e l l a s a l l t h r e e t y p e s o f m u l t i p l e x i n g :
bottles-per-sample multiplexing, samples-per-bottle multi-
plexing, and multiple-bottle compositing. These distribution
schemes are available for both bottle groups. Because STORM
programming is part of the extended programming mode, the
sample distribution displays used (Display #s 30 and 31) are
identical to other extended mode programming routines. Refer to
Example Time-Paced Multiplexed (samples-per-bottle) Sampling
for samples-per-bottle multiplexing, Example Extended
Flow-Paced Multiplexed (bottles-per-sample) Sampling for
bottles-per-sample multiplexing, and Example Flow-Paced Sam-
pling / Time-Based Bottle Sets for multiple-bottle compositing.
To enter a sample volume for the first bottle group, enter the
volume in Display #50.
The second section contains input displays for the second bottle
group. It includes displays that:
• Set the pacing for the second bottle group.
• Determine when the sampler begins filling the second
bottle group: during the same time period as the first
bottle group or after it fills the first bottle group.
• Set the maximum flow interval.
• Determine the sample distribution for the second bottle
group: samples-per-bottle multiplexing,
bottles-per-sample multiplexing, or multiple-bottle
compositing.
