QuickTrace® M-8000 CVAF Mercury Analyzer
Depending on your laboratory's requirements, the QuickTrace®
M-8000 mercury analyzer supports three modes of operation:
Mode 1: Cold Vapor Atomic Fluorescence Spectroscopy
Mode 2: Cold Vapor Atomic Fluorescence Spectroscopy
Single Gold Trap Amalgamation (CVAFS-SGTA)
Mode 3: Cold Vapor Atomic Fluorescence Spectroscopy
Double Gold Trap Amalgamation (CVAFS-DGTA)
The mode can be changed in software, without hardware
or tubing configuration changes.
Why is it so important to have a system that switches
between ultra-trace analysis and low mg/L analysis with
only the opening of a new method? These innovative features
save you set up time and eliminate costly mistakes.
Teledyne Leeman Labs also employs cost saving features
during the gold trap desorption such as shutting down
the flowing rinse and slowing the SnCl2 flow. These
innovative features can save the laboratory thousands
of dollars per year by reducing reagent and waste costs.
Using the proven cold vapor atomic fluorescence (CVAF)
technique combined with multi-tasking Windows® based
QuickTrace® software package, the QuickTrace®
M-8000 is one of the most stable reliable fluorescence
analyzer available today.
For ultra-trace analysis we recommend our autosampler
enclosure (ENC-500) to protect the samples from determinate
errors such as dust particles. The ENC-500 will also
protect your investment from the harsh acid gases normally
present in and around digested samples.
Excellent short and long term stability are found in
the QuickTrace® M-8000 CVAF analyzer.
Less than 0.02 ng/L instrument detection limits are
typical for the QuickTrace® M-8000 gold
trap modes utilizing less than 25 ml of sample. We consistently
achieve non-gold trap instrument detection limits of
less than 0.1 ng/L utilizing less than 10 ml of sample.
- Ultra-trace detection limits (< 0.05 ng/L IDL)
- Linearity greater than 4 orders of magnitude
- Dynamic range < 0.05 ng/L to > 400 µg/L
- In Mode 1 by response comparison to a 100 ng/L standard,
the system exhibits < 0.01% memory effect of a
1 mg/L standard immediately following the ingestion
of a 1 part per million (mg/L) sample.
- In Mode 1 without employing our smart rinse technology
the system is ready to accurately measure a sample
within four minutes following the ingestion of a 1
- Mode 2 & 3 - Short term precision (%RSD @ 95%
Confidence) = 2.5% @ 5 ng/L, n=5?
