specifications are for the purpose of establishing quality, unless otherwise noted.
Bids on products of other qualified manufacturers are acceptable, provided they
are demonstrated as equal to those specified in construction, design and
suitability. Each bidder shall submit with his bid a complete brochure with
pictures on each item and shall point out specifically any deviations from the
specified items. Failure to do so may disqualify any bid. Please bid as specified
or an approved equal.
28.) A copy of the manufacturer's standard guarantee/warranty shall accompany
and become a part of this bid.
29.) There are no federal or state laws that prohibit bidders from submitting a bid
lower than a price or bid given to the U.S. Government. Bidders may bid lower
than U.S. Government contract price without any liability as The University of

Southern Mississippi is exempt from the provisions of the Robinson-Patman Act
and other related laws. In addition, the U.S. Government has no provisions in
any of its purchasing arrangements with bidders whereby a lower price to The
University of Southern Mississippi must automatically be given to the U.S.
Government.

31.) All equipment bids shall be of current production and of the latest design and
construction.
32.) Where all, or part(s), of the bid is requested on a unit price basis, both the unit
prices and the extension of the unit prices constitute a basis of determining the
lowest responsible and responsive bidder. In cases of error in the extension of
price, the unit price will govern.
33.) Should the University of Southern Mississippi close due to inclement weather
conditions, or any other unforeseen events on the bid opening date, sealed bids
will open the following business day at the same time and location.
34.) As an alternative to traditional sealed bids in envelopes, the University of
Southern Mississippi is capable of receiving electronic bid responses. While this
option is available, it is not required, and we ask that all potential respondents
keep in mind that with any electronic system there could be delays or glitches
with the submission process; therefore, the University highly encourages
traditional sealed bids which are either mailed or submitted in person. Should a
vendor choose to submit their response electronically, please follow the
instructions below using the following website:
https://www.ms.gov/dfa/contract_bid_search/Home/Sell. On this site you will find
helpful links to procurement opportunities, as well as a link to supplier
registration. If not already registered in this system, potential bidders will first
need to click on 'Supplier Registration' and follow the steps outlined (a one-time
process). Once registered, they can return to the original website and click on
'Procurement Opportunities' where they can either search by keyword for the bid
they desire to respond to or leave the search box blank and click 'Search' for a
listing of all current bids and proposals for the various
State of Mississippi offices.
Regarding construction bids, there is one additional step required during the bid
submission process. Along with the bid response and other attachments,
contractors will also need to attach their Certificate of Responsibility (COR), or a
statement that the bid enclosed does not exceed Fifty Thousand Dollars ($
50,000.00). If their COR or such statement is not attached, the bid will be invalid
and not considered.

Specifications for a Low-Background High-Purity Germanium (HPGe) Well Detector Gamma
Spectrometry System
I. Background
The University of Southern Mississippi is seeking quotations from qualified suppliers for
a complete, turnkey low-background high-purity germanium (HPGe) well detector
gamma spectrometry system to be installed in a university research laboratory. The
system will support research in radioisotope geochemistry, sediment geochronology, and
particle flux studies, including routine assay of naturally occurring and anthropogenic
radionuclides such as Pb-210, Ra-226, Ra-228, Th-234, Th-228, Be-7, and Cs-137 in
small-mass marine sediment, suspended particulate, filter, and water-column samples.
The selected supplier shall provide all hardware, shielding, software, licensing, factory
characterization, documentation, and technical support necessary to place the system into
routine operation.
II. Purpose
The purpose of this acquisition is to obtain a well-geometry HPGe spectrometer capable
of high-efficiency, low-background gamma assay of small sample masses (nominally 1 to
10 g) over an energy range of approximately 40 keV to 2000 keV, with sufficient
sensitivity to quantify environmentally relevant, low-activity radionuclides at the levels
encountered in coastal and open-ocean sediments and particulate matter. Well geometry
is required to obtain near-4-pi counting geometry for limited sample quantities, and
heavy low-background shielding is required to achieve minimum detectable activities
suitable for geochronology and export flux applications.
III. General Performance Specifications
The system shall consist of a low-background HPGe well detector of at least 25% relative
efficiency and at least 130 cm3 active volume, a vertical cryostat and liquid nitrogen
dewar assembly, a digital multichannel analyzer with integrated signal processing and
detector bias supply, a low-background lead shield of at least 4 in. wall thickness with a
graded liner, and a gamma spectroscopy software suite that includes computational
(source-free) efficiency calibration for non-standard sample geometries. All components
shall be new, currently in production, and fully supported by the manufacturer. All items
shall be mechanically and electrically compatible as delivered, and the supplier is
responsible for confirming that the detector, cryostat, dewar, shield entry port, and
electronics form a functional assembly. Suppliers shall demonstrate proven experience

supplying well-geometry HPGe systems to low-level counting laboratories. Pricing shall
be itemized by line, with optional items quoted separately from the base system total.
