  • Page 5: Introduction

    1.0 INTRODUCTION The LFS-113 series sampler provides a rugged, reliable and compact sampling system for industrial hygiene and environmental sampling employment of single or multiple sorbent tubes and gas sampling bags. Two low flow modes of sampling allowconstant flows from 5-200 cc/min., as well as constant pressure for multiple sorbent tube sampling from 1-350 cc/min.

    1.2 General Description (see figures 2 and 3) Item Nomenclature Description Charging Jack Receptacle provides means of connecting charger for recharging internal battery pack. Pump Filter 10 Micron Nylon filter protects pump assembly from dirt. Discolora- tion indicates need for filter replacement. Mode Indicator Visually confirms mode engagement via Black or White indication.

  • Page 9: Set-Up

    Filter Assembly clockwise. Do Not Overtighten. 3.0 Operation The LFS-113 is a dual mode sampler, providing low flow air sampling in Constant Flow or Constant Pressure (multiple flow) modes. In the "Constant-flow mode, the unit is externally set from 5-200 cc/min.

  • Page 10: Constant Flow Sampling

    Look into the mode indicator window on the side of the sampler to see that the indicator is black or white, depending on the mode desired.Continue turning the selector switch counter- clockwise until the desired mode has been set. Now, lock the rotor into position by rotating the key clockwise - a half turn.Tighten Gently - Do Not Overtighten! The samplers mode indicator will have appeared either black for "Constant-Flow"...

  • Page 11: Multiple Flow Sampling

    Setting flow in the "Constant-flow" mode is accomplished by adjusting the flow adjust valve located on the front of the sampler. To set the flow, connect a piece of 1/8" ID tubing from the inlet of the Flow Controller Tube Holder, to the suction side of a low range rotameter, (see figure 4).

  • Page 12: Performance Checks

    Make sure that the pump is in the "Constant-flow mode, (refer to Section 3.1for complete mode selection procedure).A simple method of quickly checking constant flow performance is provided by Gilian's Low Flow Industrial Hygiene Calibrator Pack (LIHCP). Attach the pump into the LIHCP or similar calibration set-up, (see figure 6). If you are using the LIHCP calibrator: open the shut off valve (V1).

  • Page 13: Battery Performance Check

    Switch the sampler into the "Constant-pressure" mode,( see Section 3.1 for complete indexing procedure). Attach the pump into the test set-up as shown in figure 6. If you are using the Gilian LIHCP calibrator: close the shut off valve (V1). Close Load Valve (V2). Observe the O, ± 2%". Slowly open pressure on the magnehelic gauge (P1).

  • Page 14: Replacing The Battery

    scheduled to be used for long periods of time, (more than 2 months), it is recommended that the following procedure be followed on a periodic basis. a) Run pumps until they shut down on low battery. b) Recharge the battery overnight (16) hours and return the pumps into storage. 5.2 Replacing the Battery: (refer to figure 7) Place the sampler face down on a soft, level surface.
