使用DMA-80直接测汞仪测定临床样品（血液尿和头发）中的

Approximately 2700 6000 tons of mercury are released into the at
mosphere annually. Once airborne, mercury can travel thousand mile
s from its generation point. Eventually, it precipitates onto the l
and and water. And once it enters water, mercury is transformed by
microorganisms into methylmercury, the most toxic and dangerous for
m of mercury.

Exposure to high dosage of methylmercury can cause tremors, inabili
ty to walk,
convulsions and even death. Children exposed to the mercury show a
variety of
abnormalities such as delayed onset of walking and talking, cerebra
l palsy, and slowed neurological reflexes and learning abilities.

One of the best indicators of exposure to mercury is testing for co
ncentration in hair and blood. The average concentration of mercur
y in non-exposed people is about 8 ppb in blood and 2 ppm in hair

Mercury has traditionally been measured in hair, blood, tissues, an
d urine by CVAAS (Cold Vapor Atomic Absorption Spectrophotometry),
which is a time and labor consuming method that relies on complicat
ed wet chemistry sample preparation.

The DMA-80 Direct Mercury Analyzer from Milestone eliminates the sa
mple
preparation step, allowing you to rapidly process your samples in m
inutes, instead of the hours needed for traditional methods. This r
apid testing (which is as accurate, if not more so, that CVAAS) giv
es you the answers you need without consuming valuable time and eff
ort.

Other benefits include:

Process both liquid and solid samples no matter how difficult th
e matrix you will get an accurate total mercury reading.
The built-in 40-position autosampler allows unattended operation fo
r a large number of samples
The DMA-80 is portable enough to be stationed where you need it mos
t; in your laboratory, in a portable testing van, etc...
No chemicals are used in the process so no additional toxic wastes
are generated.
