Environmental
Sciences Laboratory (ESL), Brooklyn College of
The City University of New York
The laboratory and offices consist of eight rooms
occupying about 4,000ft2 on the 5th floor of Ingersoll
Hall at Brooklyn College. The ESL is equipped
with state-of-the-art instrumentation for the
analysis of inorganic particulates. These particulates
can occur as bulk powder be collected as an aerosol
or recovered from human/animal tissue. In addition
the laboratory possessed an extensive collection
of reference standards.
For
mineral characterization the Laboratory is equipped
with:
-
Analytical
Transmission Electron Microscope – JEOL –
2010 – this 200kV microscope is a multi –
purpose high resolution (1.94 Å point resolution)
analytical transmission electron microscope
with a wide range of capabilities, such as
high resolution image observation, microarea
x-ray for elemental analysis, versatile analysis
by convergent – beam electron diffraction
and analysis of the atomic structure and/or
binding sites of atoms. For energy dispersive
analysis the microscope is equipped with a
Princeton Gamma tech IMIX ultrathin window
Prism digital detector capable of detecting
elements as light as beryllium and a digital
camera from Advanced Microscope Technology
for image capture.
-
JEM
version 1.0629-W2001 PC-based transmission
electron microscopy software for the calculation
and analysis of select area electron diffraction
and high-resolution electron microscope images.
-
Compaq
Presario 1200 MHz Athlon processor with 512MB
RAM and 60G Hard Drive.
-
Continuous
scan x-ray diffractometer – Philips analytical
X-ray X-pert-MPD Diffractometer equipped with
a Peltier cooled solid state and miniproportional
detectors.
-
X’Pert
Plus Version 1.0, 23.4 1999 program for crystallography
and Rietveld Analysis, Philip Analytical B.N.
-
Polarized
Light Microscope – Zeiss AxioLab Polarized
Microscope equipped with a Minolta Camera.
In
addition the Laboratory has equipment for the
characterization of mineral surface properties
(Zeta Meter/Perkin – Elmer Lamda 2 UV/VIS Spectrometer),
mills and glassware for lofting aerosol fractions
from bulk powders, equipment for the collection
of air samples and their preparation for analysis
by light and transmission electron microscopy
(personal air sample pump and area sample pumps,
Denton Vacuum Evaporator, SPI Plasma-Prep II,
laminar flow biohazard cabinet), recovery of inorganic
particulates from tissue samples (high speed centrifuge,
hot water baths, 2 sonicators ultracell disrupters).
A complete tissue culture facility with a Zeiss
IM35 inverted microscope equipped with epiflourscence,
phase-contrast, Hoffman Interference Optics and
a Contax 35mm camera, CO2 incubator, sterile hood,
various water bath shakers, high-speed centrifuges,
and a pH meter.
