Product Specifications

Thermo Scientific NITON XLi and
XLp 300 Series analyzers are the
industry standard for lead analysis
in applications ranging from paint, to
soils and sediments, to dust wipes
and air filters, to screening for the
presence of lead in ceramic goods
and children’s toys.

Thermo Scientific
NITON® XLi/XLp 300
The Ideal Tool for Lead Analysis

Thermo Scientific NITON 300 Series analyzers provide
many distinct advantages:
•t Easy to use - by anyone, anywhere
•t Integrated barcode reader for fast, easy data entry
•t Portable GPS integration for real-time contamination mapping
•t High-strength, rugged, environmentally sealed housing

Unparalled performance for residential lead inspection.

Government regulations, increased public
awareness and legal action have all
driven requirements for the identification
of lead hazards in the environment. With
documented effects such as diminished
learning abilities in children, kidney
and central nervous system damage,
and reduced fertility and miscarriages,
researchers have concluded that there is
no safe level of lead exposure.1
Public health officials, environmental
professionals and community activists
face an overwhelming challenge: pinpoint
lead’s location in the environment, identify
the sources of contamination, and confirm
that clearance criteria have been achieved
after abatement. The traditional approach
of field-based sample collection, combined
with laboratory analysis, has been
largely replaced with the use of handheld
equipment, effectively bringing the lab
into the field. Thermo Scientific NITON
x-ray fluorescence (XRF) analyzers quickly
identify and quantify lead in virtually all
sample types: paint, soil, sediment, dust,
air, and more. They can be used effectively
for screening for the presence of lead (not
quantifying lead levels) in ceramic goods
and children’s toys. Articles should be sent

to a lab for further testing if lead is detected.
Supported by a Performance Characteristic
Sheet (PCS) documenting zero inconclusive
readings, zero need for substrate correction,
and zero false positives/false negatives,
the NITON 300 Series determines whether
lead is positive (as defined by the US EPA
as greater than or equal to 1.0 mg/cm2), or
negative in seconds. Users in jurisdictions
with more stringent standards can easily
change the action level to ensure compliance
with local regulations. Actual lead values
are also displayed, permitting users to more
accurately quantify the hazards associated
with particular samples.
The analysis of lead dust poses another
challenge. Widely acknowledged as the
primary source of childhood lead poisoning2,
lead dust is hazardous even in very small
amounts. Standard practice involves collecting
the dust on an ASTM-approved towelette
wiped over a one-square foot area (929
cm2), followed by analysis of the “wipe” for
determination of the lead load; dividing the
reported lead content by the area yields a
lead-dust concentration in µg/ft2. The NITON
300 Series XRF analyzer offers the ability
to perform this analysis on site using the
optional Dust Wipe Analysis Mode.
