High flows from 5 to 15 L/min
Achieve flow rates that you couldn't reach before when using a personal sample pump. The Leland Legacy provides the high flows and long run times of a vacuum-style pump in a compact, portable, battery-operated sampler within specified back pressure range. NOT for applications requiring instrinsic safety or high back pressures.
Long runs for 24 hours on one battery charge
Rechargeable lithium-ion (Li-Ion) battery pack provides 24-hour run times with impactors and other sampling devices with low back pressures.* Leland Legacy is ideal for 24-hour indoor air studies and unattended ambient air sampling.

Leland Legacy is not recommended for high back pressure applications such as asbestos clearance sampling. |
Typical Run Time†
24+ hours:
- Sioutas Impactor at 9 L/min (approximately 13 inches water back pressure)
- Respirable PPI at 8 L/min
- Low-volume PUF Tube at 5 L/min
- IMPACT Sampler (PM2.5 or PM10) at 10 L/min
- For extended run times, the pump may be operated while attached to the approved charger.

Results obtained using a new pump and new fully charged battery. Pump performance may vary. |
Low Levels
Longer runs at higher flows provide more sample for the enhanced sensitivity required for measuring low concentrations, particularly in indoor air environments.
Low Noise
With the noise-reducing case accessory, the Leland Legacy can operate at 10 L/min and 12 inches water back pressure with a noise level of only 52 dBA.**
** Measured 3 feet (1 meter) from pump operating at 10 L/min without media
Advanced flow control
The highly accurate internal flow sensor measures flow directly and acts as a secondary standard to constantly maintain the set flow. Set flow is achieved immediately at start-up and flow rate verification is automatically maintained by built-in sensors that compensate for differences in temperature and atmospheric pressure during sampling.
Flexible programming
- Manual three-button operation
No tools needed. Simply use the Leland Legacy built-in keypad to set, calibrate, and sample! Real-time sampling parameters are available at the touch of a button.
- PC programmability
The ultimate in pump scheduling and record keeping. Use Leland Legacy with your PC and DataTrac for Leland Legacy Software to create complete running sequences, download sampling and flow rate verification data, and generate sampling reports for ISO 9000, Total Quality Management (TQM) programs, and occupational health and safety management systems. DataTrac Software for Leland Legacy is included in the 5-pack kits and sold separately.
The Leland Legacy Advantage
Collects more sample
High flows and long run times greatly increase the amount of particulate matter collected when sampling low levels. This enhances the usefulness of the data for environmental health and epidemiology studies.
Designed for indoor environments
Noise, size, and weight are minimized relative to the high flow range.
Downloadable history
Critical sampling parameters are retained in memory during the sampling period and can be downloaded for record keeping.
Leland Legacy and Sioutas Impactor* 
Suitable for use with the Leland Legacy Pump at 9 L/min, the Sioutas Impactor separates airborne particles precisely into five size ranges from ultrafine to PM2.5. When used with PTFE filters, the Sioutas Impactor is highly efficient at collecting particles without using impaction grease or coated substrate and at retaining unstable compounds for size-fractionated chemical analysis. The performance of the Leland Legacy pump with the Sioutas Impactor has been verified through EPA-ETV.

Leland Legacy and Sioutas Impactor Receive ETV Verification
U.S. EPA Environmental Technology Verification (EPA-ETV) is a program that furthers environmental protection by accelerating acceptance and use of improved, cost-effective technologies through performance verification. EPA-ETV tested the performance of the SKC Leland Legacy Sample Pump with the Sioutas Impactor.
The SKC Leland Legacy and NUATRC
The Leland Legacy was developed in partnership with the Mickey Leland National Urban Air Toxics Research Center (NUATRC) to further advance personal exposure measurement.
Established by Congress in the Clean Air Act Amendments of 1990 (CAAA), the non-profit Leland Center is responsible for investigating public health risks posed by air toxics to urban populations. The Leland Center is a private/public research partnership that brings together corporate, academic, and government scientists to develop a sound peer-reviewed air toxics research program. This program is jointly supported by the private sector and the U.S. EPA.
