INTRODUCTION The SKC Deployable Cartridge Sampler (DCS) System is a compact, portable, and battery-operated sampling system that ensures the ability to sample gaseous polycyclic aromatic hydrocarbons (PAHs), polyhalogenated dibenzo-p-dioxins (PHDDs), and polyhalogenated dibenzofurans (PHDFs) and particulate-associated PHDDs and PHDFs in ambient air. The system features the fully programmable constant flow Leland Legacy Sample Pump and an easy-to-use sampling head that houses a stainless steel cartridge.
PERFORMANCE PROFILE Flow Rate: 10 L/min Run Time: > 24 hrs on one battery charge Power: Rechargeable lithium-ion (Li-Ion) battery, 7.4 V, 12-Ah capacity†, 88.
PRINCIPLE OF OPERATION A sample pump draws air at a flow rate of 10 L/min through nozzles on top of the sampling head and into the cartridge. The cartridge is designed to be loaded with a cleaned 47-mm quartz filter that collects particles and cleaned PUF or XAD-2 sorbent that adsorbs gases and vapors. The aluminum foil-wrapped cartridge is supplied in a PTFE jar so that the sample is protected from light and contamination during transport.
MEDIA PREPARATION For Laboratory Use Use clean hexane-rinsed PTFE-tipped forceps to handle filters. Wear disposable, clean, lint-free nylon or powder-free surgical gloves to handle the sorbent and cartridge. Quartz Filter: Prepare following the procedure outlined in EPA TO-9A or TO-13A, Section 10.2.1. (http://www.epa.gov/ttnamti1/airtox.html) XAD-2 Sorbent: Purchase precleaned or use procedure outlined in EPA TO13A, Section 10.2.5.
Deployment of Cartridges for Field Sampling Immediately prior to field deployment, follow the procedure in EPA TO-9A or TO-13A, Section 10.4. SAMPLING HEAD PREPARATION Cleaning the Sampling Head All cleaning, loading, and unloading should be conducted in a controlled environment to minimize any chance of potential contamination. When new or when using the sampler at a different location, all sample contact areas need to be cleaned. Rinse with appropriate organic solvent.
Inserting a Cartridge into the Sampling Head Wear disposable, clean, lint-free nylon or powder-free surgical gloves to handle the sorbent and cartridge. 1. Disassemble sampling head (see drawing on page 3 for placement of parts). a. Unscrew inlet section from cartridge holder section. b. Unscrew cartridge holder section from exhaust section. 1 Inlet section Clean and allow to dry (see Cleaning the Sampling Head on page 5). 2. Cartridge Exhaust holder section section Disassemble sampling head.
SAMPLE PUMP OPERATION The user may choose to: • Operate the pump manually in the field (on/off ) • Program a schedule into the pump manually • Program the pump for multiple schedules from a PC with optional DataTrac® for Leland Legacy Software (see Ordering Information, Accessories on page 14). See page 9 for a Quick Guide to operate the SKC Leland Legacy Sample Pump. For advanced programming, see the complete Leland Legacy Pump Operating Instructions.
battery from charger and connect pump to battery (see Battery Setup below). After charging the battery pack, it is good practice to run the pump for approximately 5 minutes before calibrating. This ensures the battery is in more steady-state conditions and improves the agreement in pre and post-sampling calibrations. Reading the Charging Status LED Power supply jack The Li-Ion Charging Unit indicates battery charge status via an LED on the unit that blinks in specific patterns.

CALIBRATION AND SAMPLING Calibration Calibrate pump flow rate with the sampling head loaded with a cartridge in line. See pump and calibrator operating instructions. Wear disposable, clean, lint-free nylon or powder-free surgical gloves to handle the sorbent and cartridge. Ensure pump has run for 5 minutes before calibrating. Ensure rain cover is removed from inlet and that sampling head is completely assembled with a fully loaded cartridge (see Inserting a Cartridge into the Sampling Head).
Sampling Locate system in an unobstructed area, at least 6 feet (2 meters) from any obstacle to airflow. Wear disposable, clean, lint-free nylon or powder-free surgical gloves to handle the sorbent and cartridge. Before use, allow pump to equilibrate after moving it from one temperature extreme to another. 1. Attach mounting bracket at the desired location and at breathing zone height (6 feet or 2 meters) using wire ties or other fasteners.
SAMPLE REMOVAL, SHIPPING, AND ANALYSIS Removing the Cartridge from the Sampling Head Wear disposable, clean, lint-free nylon or powder-free surgical gloves to handle the sorbent and cartridge. 1. Unscrew inlet section from cartridge holder section. Ensure cartridge remains vertical to avoid loss of sample from filter. 1 Remove inlet section from cartridge holder section. 2. Lift cartridge from cartridge holder section. Lift cartridge from cartridge holder section. 3.
Removing Filter and Sorbent from Cartridge For Laboratory Use Only 1. Remove filter and sorbent(s) from cartridge. 2. Combine for extraction. 3. a. For XAD-2 sorbent: Use procedure outlined in EPA TO-13A, Section 12.2. b. For PUF sorbent: Use procedure outlined in EPA TO-9A, Section 12.1.
