Laboratory
Facilities and Field Sampling Capabilities
My laboratory is located at SCSU in Jennings Hall 314. The laboratory
is equipped with equipment and supplies necessary for the conduct
of our studies of contaminant metals in coastal sediment
and organisms.

The lab is equipped with two bench top laminar airflow stations. Both units contain a prefilter and a HEPA filter to provide air that meets or exceeds ISO 14644 Class 5 Clean Air requirements.

Acid extractions of metals from sediment samples are conducted
in
vented fume hoods in the laboratory.

Type I reagent quality water purification is accomplished with an
E-pure 4-Module System with pretreatment.

Freeze drying is accomplished using a FreeZone 4.5 liter freeze dry system.

Sediment and tissue analyses are analyzed for mercury using a recently acquired
Milestone Direct Mercury Analyzer DMA 80.
Matthew
Cacopardo analyzes a digest sample using an air-acetylene flame
on the PerkinElmer AAnalyst 800 atomic absorption spectrophotometer.
This instrument, located in JE 325, is equipped with an automated
motorized atomizer, allowing the switching between flame and furnace
by software command. The instrument is equipped with a transversely
heated graphite atomizer (THGA) with longitudinal Zeeman effect
background correction. The graphite furnace system includes true
temperature control and integrated platform tubes providing STPF
conditions for almost interference-free trace metal analysis. The
AAS system is interfaced with a PC with WinLab32 software. The system
is also equipped with a MHS – 15 Mercury-Hydride System. The
MHS-15 Mercury/Hydride System is a manual accessory for high-sensitivity
determination of mercury and hydride-forming elements, such as As,
Se, Sb, Te, Bi and Sn, by flame Atomic Absorption Spectrometry.

Sediment sampling is accomplished using a ponar grab.
A
brief video of the sediment sampling process is available here.

Sediment cores (2” x 20”) or (2” x 36”)
are obtained using a Wildco Hand Held Stainless Steel Corer. The
corer is lined with plastic core tubes to allow easy extraction
and storage of the sediment core.
A
brief video of the sediment coring process is available here.

Access to Connecticut harbors and Long Island Sound for sediment
sampling
is
provided by the R/V Island Rover.
