LPA-1 XRF Lead Paint Inspection Analyzer

X-Ray Fluorscence Spectrum Analyzer

RMD XRF spectrum analyzer system for analyzing lead paint

The RMD LPA-1 Lead-Based Paint Analyzer is a state-of-the-art XRF spectrum analyzing system for measuring lead in paint on any surface. The LPA-1 Analyzer provides fast, accurate measurement of lead content in as little as 2 to 4 seconds with a 95% confidence level, thereby assuring the highest level of productivity for an inspector.

The advanced design of the LPA- 1 represents a new generation of XRF system. By employing technological advances in the fields of electronics and microprocessors, and combining them with knowledge gained from experience with existing X-ray fluorescence technologies, the LPA- 1 can make accurate assessments of lead levels in a fraction of the time previously needed. The result is the most effective lead inspection system available today.

The LPA- 1 method of measurement is based on the spectrometric analysis of lead K-shell X-ray fluorescence within a controlled depth of interrogation. Various studies have concluded that K-shell x-ray measurement of lead in paint is more accurate and the preferred method for XRF analysis. Unlike L-shell X-rays, K-shell X-rays can easily go through the paint without being affected by the thickness and the composition of various layers of paint that can cause false readings. The controlled depth concept used exclusively in the design of the LPA- 1 restricts the penetration of the energetic K-shell X-rays into the substrate to 3/8" so that the system cannot be mislead by the presence of lead pipes or other objects located deep in a wall.

The LPA- 1 system has gone through satisfactory CRCPD device safety reviews for distribution under both Specific and General licenses.

The LPA-1 Advantages 

  •  K-Shell XRF has no L-Shell limitations (see HUD Guidelines Chapter 7). 
  •  Compact footprint fits where other systems can't such as window tracks & wells, and narrow moldings. 
  •  Measurement depth of 3/8" means no false positives due to hidden pipes in walls, or readings on the other side of walls or doors. 
  •  18 hour system battery life puts in a long days work. 
  •  Quick battery charge time of 1.5 hours without NiCad memory problems or possibility of overcharge. 
  •  Stores up to 4,000 readings 
  •  Weighs less than 3 lbs with battery 
  •  Selectable action level 
  •  Highly reliable solid state CdTe sensor 
  •  2 Years parts and labor warranty 
  •  Fast readings without decision trees 
  •  Automatic substrate correction 
  •  Maximizes productivity and reduces job time

LPA-1 with HP iPac Running the Portable Data Recorder Software

RMD’s Portable Data Recorder (PDR) option is a low-cost, lightweight data-entry solution for lead inspectors in the field.  The PDR is designed to run on a hand held PC running Windows® CE.  It allows the lead inspector to quickly and easily gather data in the field without any limitations.  PDR interfaces with RMD’s Report Generation Software (RGS), streamlining data entry and allowing the inspector to produce reports more quickly and efficiently.

 

Features include the following.

  •  Lightweight HP iPac PDR option.
  •  Fully customizable software. 
  •  Create your own structures, substrates, and more. 
  •  Auto save feature prevents data loss. 
  •  Auto reminder feature keeps you synchronized with your LPA-1. 
  •  Enter calibrations, comments, and cover sheets. 
  •  View your work with preview feature. 
  •  Export your data as comma-delimited text. 
  •  Interfaces with the RMD software or
  •  Download & merge the LPA-1 data directly to the PDR.. 
  •  Easy merge feature to laptop or standard PC.

Operating Modes: Flexibility & Speed of Measurement

LPA-1 XRF Lead Paint Analyzer's Quick Mode

 

There are three measurement modes of operation in the LPA- 1 analyzer:

  •  Standard Mode
  •  Quick Mode
  •  Time Corrected

In "Standard Mode ", the operator selects a fixed measurement time which remains constant regardless of the lead signal.

 

LPA-1 Quick Mode Readings in 2-4 Seconds

 

In "Quick Mode", the analyzer seeks the shortest period of time to assure a definitive measurement with 95% confidence (2sigma). The LPA- 1 analyzer concludes a measurement once the 2 sigma confidence level is achieved, typically between 2 to 4 seconds depending on the action level and the lead content.

For calibration checks, the user selects the "Time Corrected" mode. The Time Corrected mode is a 30-second Standard Mode equivalent time corrected for the life of the source.

The fast analysis capability of the LPA-1 analyzer is complemented with a data storage capacity of 4000 data points. After completing the lead inspection, the measurement results may be transferred from the LPA-1 to a computer at the inspectors convenience via an RS-232/USB communication link. The easy to use LPA- 1 Report Generating Software creates a simulation of the actual inspection site with icons for doors, windows, steps, etc.

Manual or Interactive Mode

The LPA-1 can be used in either the "Manual: or "Interactive Mode". The Interactive Mode allows the user to input all the sample parameters and notes, and at the completion of an LPA-1 reading, that lead value is sent directly from the LPA-1 to the HP iPac PDR system. Therefore, all lead inspection report information is contained in the PDR system streamlining the Inspection Report production process.

Manual Mode is used independent of direct connection to the LPA-1. Manual Mode allows the user to enter all the reading parameters into the PDR system and then quickly transferred, merged with the LPA-1 readings and opened using the report generation software (RGS) to produce the Lead Inspection Reports.
