Automated SPE technology forwater analysisThe AutoTrace SPE
Workstationautomates the time-consuming andoften error-prone steps
in Solid PhaseExtraction (SPE) of trace contami-nants from water.
Through the use ofprecision syringes, pumps, and easy-to-use menu
software, the AutoTraceprocesses up to six water
samplessimultaneously. Sample volumes canrange from as low as 10 to
as high as2 1; and five reagents can be used forconditioning and
elution steps. TheAutoTrace uses 1, 3, 6 or 8 ml syringebarrel SPE
cartridges, which can bedried with an inert gas ifdesired.
Theeluent receiving containers can bestandard 16X100 test-tubes,
WISPor GC vials. The waste stream separ-ates the water and organics
for easierand less costly solvent disposal.
The conditioning, sample deliveryand elution steps are
microprocessor-controlled, which improves the preci-sion of the
results. The unit runs withits own internal operating system
nodedicated computer is necessary.The methods are developed on
apersonal computer using pull-downmenus. The software easily
accomo-dates multiple elution steps from asingle SPE cartridge with
minimalmanual intervention to change thereceiving tubes.

Networking software
Hewlett-Packard’s HP ChemLAN(DOS Series) networking software
isdesigned to link HP ChemStation(DOS Series) applications (gas
chro-matography, mass spectrometry andliquid chromatography) on
astandards-based network. Thisallows R&D, QC, QA and
otherlaboratories with a high throughputof samples to increase data
analysiscapabilities by using client/servercomputing.
Zymark’s Auto Trace SPE Workstation, which can process over 24,
one litre water samplesin an eight hour shift and requires only 15
minutes of operator time (see text).
HP ChemLAN (DOS Series) soft-ware offers a number of
advantages,for example: automatic DOS-to-DOS HP ChemLAN
sequencing;automatic DOS-to-DOS printing,including graphics;
transparentremote network file system (NFS)access to HP-UX*
systems; andsimultaneous client/server function-ality.The automatic
DOS-to-DOSHP ChemLAN sequencing functionof the HP ChemLAN (DOS
Series)server software reduces both analysisand reporting time and
allows labor-atories to increase throughput. Whendata acquisition
is completed on oneHP ChemStation, the data, alongwith the
sequence, are sent automati-cally to another HP ChemStation onthe
network, where analysis andreporting are performed withoutoperator
intervention. The dataacquisition ChemStation continuesto collect
new data while the report-ing ChemStation processes it. Mul-tiple
HP ChemStations across thelaboratory can acquire data for
auto-matic transfer to a single reportingChemStation.
HP ChemLAN (DOS Series) serversoftware allows automated,
remoteDOS-to-DOS printing, eliminatingthe need for a separate
printer at eachworkstation and providing the whole
laboratory with access to high-quality printing. Reports
includinggraphics such as chromatogram andspectra, word processed
documentsand spreadsheets can all be printedfrom HP ChemStations or
any otherDOS-based system running HPChemLAN (DOS Series) client
soft-ware and Microsoft Windows.Unlike many print servers, the
serverrunning HP ChemLAN (DOS Ser-ies) need not be dedicated
toprinting.
HP ChemLAN (DOS Series) sof-tware also give laboratories
transpar-ent access to remote disks throughNFS functionality,
making it easy forsystems to share method, data andsequence files
while maintaining filesecurity. Laboratories can access fileson an
HP-UX ChemSystem just as ifthey were on the local system. NFSalso
provides password protection.
A new feature of HP ChemLAN(DOS Series) software is its ability
torun client and server network pro-grams simultaneously, resulting
insignificant gains in laboratory pro-ductivity. HP ChemLAN users
cannow send and receive information atthe same time; for example,
they canreceive data over the laboratorynetwork while sending a
final report

Cell Robotics, Inc.
Cell Robotics, Inc. have announcedtwo new products: the
Laser-Tweezers 1000 system for opticaltrapping and
micromanipulationand the FT 1000 Fourier transformspectral imaging
system.
The LaserTweezers 1000 converts astandard inverted microscope
into alaser-based optical trapping system.This system can then be
used to trap,levitate and manipulate single cellsand other
microscopic particles (forexample chromosomes). An infra-reddiode
laser is used as the trappingbeam, so that these manipulationsare
performed without physical con-tact or damage to the cell.
The LaserTweezers is useful in awide varity of research
applications.Rare cells, chromosomes or othermicroscopic particles
can be separ-ated with absolute purity. Selectedcells can be placed
in contact withone another so as to analyse theirinteractions.
These and other oper-ations are. performed entirely withinCell
Robotics’ proprietary cell man-ipulation chamber.
The FT 1000 spectral imagingsystem represents a new generationof
fluorescence microscopes. Its pri-mary function is to image the
spatialdistribution oflarge numbers ofspec-tral parameters and
fluorescentprobes. It does so without usingoptical filters or beam
splitters,resulting in minimum light loss and agreatly simplified
optical layout.This is an instrument that can beused for a
multitude of biologicalapplications in which it is importantto
identify and/or characterizecertain types of cells and
cellularstructures that have been labelledwith fluorescent
probes.
