MAGSAM 2000
The MAGSAM 2000® comprises a strong,
rare earth magnet housed in a stainless steel casing to provide
a robust and convenient sampling method. The long shaft and
retracting magnetic plunger result in a clean sample that
does not contaminate the following sample. The magnetic lag
fraction can be easily deposited into a conventional kraft
soil sample packet or zip-top plastic bag. Magnetic lags represent
a standard geochemical method, commonly used in stream sediment
sampling programmes with potential applications to regional
soil/MAGLAG sampling.
Major Advantages Include:
- Compact size and increased field
strength compared with conventional magnets.
- Samples a common medium (maghemite
and associated Fe hydroxides) across a changing regolith
terrain.
- Potentially increases anomaly size
and decreases geochemical "noise" affording confidence
in a much wider sample spacing, i.e 1 to 2 samples/km2.·
Potential applications to partial digestion techniques analysing
for Au plus a multi-element suite.
- Small sample size required - 10
to 20 gm (even for low level Au analyses) helping to minimise
freight costs and potential customs/quarantine problems
for overseas jobs.
- Can be used underwater in stream
sediment sampling programmes.
- Relatively low cost - AUS$308 (includes
GST) within Australia and US$280 exported around the world
(export price includes air freight costs).
