3700 Portable Samplers
Section 3 Programming Guidelines
3-34
Example Time-Paced Composite Sampling demonstrates the pro-
gramming procedures for a composite sampling routine. When
composite sampling with the 3700 Standard, you must convert
the unit for single-bottle sampling. With the 3700 Compact, you
must install the proper bottle into the base.
After converting the 3700 Standard, check the settings to verify
the sampler is configured for composite sampling. This example
begins with a demonstration of the steps needed to check the
Bottles and Sizes configure option settings. The Bottles and Sizes
configure settings should indicate that only one bottle is being
used. Be sure to enter the correct bottle volume. The settings
used in this example are for the 4-gallon (15,000 ml) composite
bottle available with the 3700 Standard.
This time-paced routine will take samples at 15-minute intervals
for a 12-hour period. Sample volumes are to be 250 ml each.
When entering the program settings, you must enter the number
of samples required before entering the sample volumes. At four
samples per hour, the 12-hour period would yield 48 samples.
The total sample volume collected at the end of the routine would
be 12,000 ml (48 samples
x
250 ml/sample), well within the
capacity of the 4-gallon bottle.
