At pION s analytical services laboratory, the pKa of a molecule (whose structure may not be known beforehand) is first measured by the TFA method, because very little sample is consumed. (Sometimes there is not much more than 1 mg of sample with which to work.) Only when the analysis of the data proves problematic do we repeat the measurement, the second time using potentiometry, where more sample is required. If any indication of precipitation is evident, either DMSO or methanol is added to the titrated solution and the titration is repeated 3 times (using the same sample), with additional water added between the repeats, to obtain different Rw values of the mixed solvent solutions. It has been our experience that if the TFA method fails and more sample is available, the follow-up pH-metric method always works. 

Table II demonstrates how NPV would be calculated for a hypothetical LIMS, purchased as a package with negligible site preparation and with installation costs included in the purchase. It is to be acquired for a service laboratory primarily supporting R D activities but with some minimal process monitoring responsibilities. The IRR for this project could be found by trial and error determination of the yearly discount rate which results in a zero NPV. A succinct discussion of these financial management analysis tools can be found in two works by Weston and Brigham. The first (9) presents theoretical and detailed analytical expositions the second OO) is a more practical, applications oriented presentation.

Voucher at the time of drilling. The well owner then redeems the voucher by collecting the necessary water samples, using the bottles and a methodology provided by the DENV, and submitting them to the DENV Analytical Services Laboratory for a standard inorganic chemistry analysis. 

In all 28 parameters were individually mapped alkalinity, aluminum, antimony, arsenic, barium, boron, bromide, cadmium, calcium, chloride, chromium, conductivity, copper, fluoride, hardness, iron, lead, magnesium, manganese, nitrate, pH, potassium, selenium, sodium, sulphate, thallium, uranium, and zinc. These parameters constitute the standard inorganic analysis conducted at the DENV Analytical Services Laboratory. 

DuPont research into high current density and the associated effect on membrane and electrolyser performance has been underway for a decade. It has been the area of greatest concentration for the company during the last 5 years. Studies at the DuPont Experimental Station and Fayetteville Nafion Customer Service Laboratories resulted in polymer innovation and new membrane designs. This work has also identified interactions between membranes and electrolysers... 

DuPont s perspective on membrane development will be outlined. The expansion of the facilities at the Nafion Customer Service Laboratory will also be described. This expansion has been undertaken in support of DuPont s commitment to increase the understanding of chlor-alkali technology and ensure continuous improvement of DuPont s membranes. 

In its support of the commitment to increase the understanding of chlor-alkali technology and to continuously improve its membranes, DuPont has expanded its CSL (Customer Service Laboratory) facilities at Fayetteville, North Carolina in the United States. 

Prior to 1999, DuPont maintained laboratories at both ESL (Experimental Station Laboratories) in Wilmington, Delaware and the CSL (Customer Service Laboratory) in Fayetteville. In preparing for the new millennium, DuPont s business plan has provided for moving the main research function to Fayetteville and consolidating the laboratories there. These facilities are also now showing their age after a combined 35 years of round-the-clock operation.

Hj) Height of Burst (Sonic) Test. The purpose of this test is to det the height of burst of a fuze using sonic techniques. This technique requires the measurement of the time of arrival of sound at directional microphones precisely placed in a plane. A brief description of this test is given on p IIIB-20 Ref 39 Addnl info can be obtd from "Instrumentation Section, Technical Services Laboratory, Ammunition Development Division, Ammunition Engineering Directorate, Picatinny Arsenal, Dover, NJ 07801 H2) Hydraulic Ram and Vibrator Test. This test could be used to simulate impact shock on bombs or rockets assembled with fuzes that are launched from aircraft. It also could check the transportability of fuzes that experience this environment. This test is listed, but not described in Ref 39, p IIB-37...

Calibration of the intensities of the radiation flelds is traceable to the NIST. The ionization chambers and electrometers used by the service laboratories to quantify the intensity of the radiation fields must be calibrated by the NIST or an accredited secondary standards laboratory. The intensity of the field is assessed in terms of air kerma or exposure (free-in-air), with the field collimated to minimize unwanted scatter. Conversion coefficients relate the air kerma or exposure (free-in-air) to the dose equivalent at a specified depth in a material of specified geometry and composition when the material is placed in the radiation field. The conversion coefficients vary as a function of photon energy, angle of incidence, and size and shape of backscatter mediiun.

The coal service laboratory, which in the past was concerned with determining the ASTM Procedures for Ultimate and Proximate Analysis, is now responsible for analyzing trace elements in coal. With this sort of facility and technical skill in mind, our own wet chemical laboratory devised relatively routine procedures for determining trace elements in coal that could have an undesirable environmental impact including Hg, Be, Se, As, Cd, Pb, F, Cu, Ni, Zn, Cr, Te, Ge, Mn, Sn, B, Bi, Sb, V, Li, Co, and Ag. 

As a result of this investigation of wet chemical procedures, I believe that a coal service laboratory, with a modest increase in instrumentation, can essentially determine all the significant trace elements with the necessary precision and sensitivity. 

The authors are indebted to the National Research Council of Canada for grants-in-aid of this research to R. U. Lemieux (A-179) and postgraduate scholarships to John Brewer. The NMR, infrared, and micro analyses were provided by the service laboratories of this Department. The 220 MHz spectra were purchased. 

The infrared spectrophotometer is the principal instrument used by scientists for ihcse measurements. Most laboratory spectrophotometers are of a dispersive design, i.e.. a prism or grating is used to separate the spectral components in the source radiation. Modern infrared spectrophotometers base it wide wavelength range from 2 to 50 micrometers. They lind use in research, quality control, and analytical service laboratories. 

The XRF and XRD analyses were conducted by the Scientific-Technical Services laboratory at the University of Barcelona.
