    Section 1 Introduction 1.1 Introduction The 3700 Standard Portable Sampler is a programmable liquid sampler and is one of Teledyne Isco’s 3700 Series of portable and refrigerated samplers. The extensive sampling capabilities; easy, flexible programming, and durable construction make the 3700 Series ideally suited for general-purpose or priority-pollutant sampling.

    1.2.3 STORM Sampling The 3700 Series storm capabilities are ideal for monitoring storm water runoff. The sampler allows you to divide the bottles into two groups. The first group of bottles is normally reserved for a first-flush grab sample.

  • Page 17: Master/Slave Sampling

    1.2.4 Master/Slave Sampling A notable feature is the master/slave setting, which allows you to operate two 3700 Samplers as a master/slave pair. Master/slave sampler pairing doubles the capacity of a sampling installation and to perform continuous sampling. Two samplers can be connected so that one sampler (the master) inhibits the operation of the second sampler (the slave) until the master completes its sampling routine.

    1.3 Delivery System The 3700 Series uses a peristaltic pump for sample collection. The sample is under pumped flow at all times; there are no metering chambers and no gravity-fed internal tubing. Each sampling cycle includes an air pre-sample purge and post-sample purge to clear the suction line both before and after sampling.

  • Page 35 Teledyne Isco has found that the most effective way to learn to program the 3700 Sampler is to read this section with a sampler in front of you. The time that you spend in the office or laboratory actually programming the sampler and observing its operation is usually time well spent.

  • Page 36: Description Of Sampling Operation

    The 3700 Sampler is principally designed to collect sequential (discrete) samples. However, you can program it to collect a number of other types of samples. The 3700 Sampler has two pro- gramming modes: Basic and Extended. The basic programming mode is used for conventional routines, which include the types of sampling described in this section.

  • Page 37: Types Of Sample Pacing

    Flow-paced sampling requires a flow meter. (You can interface the 3700 Sampler with Isco Flow meters, flow loggers, and certain non-Isco Flow meters.) The flow meter measures the flow quantity and sends a pulse for every predetermined flow quantity to the sampler.
  • Page 38 Samples-per-Bottle Multiplexing – I n s a m p l e s - p e r- b o t t l e multiplexing, the 3700 deposits a number of individual samples in the same bottle. Samples-per-bottle multiplexing is useful when you need to collect a series of small composite samples.

    Note also that STORM programming is available only in the extended programming mode. 3.3.1 Nonuniform Time In the extended programming mode, the 3700 Sampler can pace Intervals samples at nonuniform time intervals. With nonuniform time intervals, the 3700 takes samples at irregular intervals, rather than at equal intervals.

    Sample Event Number Figure 3-4 Multiple-Bottle Compositing 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.

  • Page 43: Programming Modes

    Some configure options provide equipment specifications: bottle sizes, suction-line diameters and lengths, and so on. For example, the 3700 Standard can use dif- ferent-sized sequential bottles: 350 ml and 1000 ml. You must enter the correct bottle size so that the sampler can calculate the range of sample volumes for a given number of samples and prevent overfilling.

  • Page 221: Appendix E Calculating Flow Increment Between Samples

    3700 Portable Samplers Appendix E Calculating Flow Increment Between Samples The 3700 Sampler will accept flow-proportional inputs from an external flow meter or flow logger. These electronic flow-input signals are transmitted to the sampler at fixed increments of total flow, for example, every 10,000 gallons. Each time 10,000 gallons of liquid flows past the flow meter, it sends a signal to the sampler, which registers it as a single flow pulse.

    3700 Portable Samplers Appendix F Glossary Bottles per sample – Bottles per sample is the number of bottles receiving sample volumes at each sample event. Composite sampling – In composite sampling, multiple sample volumes are placed in bottle sets. Typically, composite sampling uses a single container.
  • Page 226 3700 Portable Samplers Appendix F Glossary Sample volume – The sample volume is the discrete, pro- grammed amount of sample delivered to each bottle. A single sample event may deliver several sample volumes. Samples per bottle – Samples per bottle is the number of dis- crete sample volumes placed in each bottle.
