The new PCE-ISFET pH meter from PCE Instruments has been designed for food applications. The glass free electrode makes it particularly safe to use in food production as no glass splinters can get into the food if the electrode breaks. Unlike glass pH electrodes, ISFET pH sensors are highly resilient and do not require wet storage. They give reliable results under tough conditions. The PCE-ISFET ...
Errors associated with the closed flux chamber technique, used to measure surface emissions from landfills, were investigated by using a combination of numerical modeling and laboratory studies. A transient-state, advective–dispersive–reactive model was developed and used in conjunction with its steady-state version to quantify the errors associated with closed flux chambers. In developing the ...
Laboratory Information management systems (LIMS) have been around for about 25 years, and many water systems use them. The challenge often Is to configure the LIMS for the specific needs of a drinking water operation. Now Thermo Fisher Scientific offers a LIMS preconfigured to help users comply with water and environmental regulatory guidelines and requirements. It Is built on the functionality ...
Industry is looking more and more to outsourcing its analytical and testing needs to contract laboratories. This places on those laboratories a need for a flexible, yet structured and error-free, means of handling and reporting sampleinformation and results. There is a key requirement to handle customer contact records, production of quotations andinvoices, and ensure proven adherence to the ...
Trustworthy, Trained, and Truthful are the 3T's that greatly influence one's decision while choosing a good asbestos lab - Is the data you are receiving accurate and can you TRUST the data being provided? Is an educated, experienced, TRAINED analyst analyzing your samples? Is the lab always TRUTHFUL and not hide any errors that might have occurred during the process? One can be assured of making ...

ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
The accuracy of incubator gases within an IVF laboratory plays a major role in success of IVF programs in any fertility clinic today. Given the crucial role that the incubator plays in the IVF process, the conditions within the incubator in an IVF laboratory must be optimal at all times to increase the likelihood of a successful assisted reproductive treatment. Geotech’s ...
(Reprinted from American Laboratory September 2004) Technologies for identifying unique items using radio waves, also known as radio frequency identification (RFID), have been available for decades. In the past, the lack of ...
Problematics The autoradiography technique consists in depositing sensitive screens collecting the radiation on facility floors, ceilings or walls during different exposure times ...
Eastern Deanery Aids Relief Program (Nairobi, Kenya) has improved data recording, speeded up sample throughput and allowed a direct link to existing electronic patient records by replacing its paper-based laboratory documentation system with Matrix Gemini LIMS. Background Eastern Deanery Aids Relief Program (EDARP) is a non-profit Christian faith-based organization which serves ...
With nearly 40 years of experience working in Life Sciences and laboratory automation systems Peter Boogaard has seen amazing improvements in optimizing business processes in the laboratory. Starting in the early 1980’s, Peter worked for PerkinElmer on new product lines associated with CAChe (Computer-aided chemistry). These new CAChe products were LIMS and chromatography data handling ...
Benchmarking At Labcore, a division of Poplar Solutions, LLC, performance management begins with benchmarking key laboratory activities that contribute to cost, quality, end-user acceptance, and other important variables. Benchmarking allows lab staff to quantify and demonstrate the improvements to laboratory operations. There are a number of metrics that ...
ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...
Abstract Many targets that remote sensing scientists encounter when conducting their research experiments do not lend themselves to laboratory measurement of their surface optical properties. Removal of these targets from the field can change their biotic condition, disturb the surface composition, and change the moisture content of the sample. These parameters, as well as numerous others, ...
The effects of limiting factors such as rainfall intensity, rainfall duration, grass type and vegetation coverage on the stormwater runoff of urban green space was investigated in Tianjin. The prediction equation of stormwater runoff was established by the quantitative theory with the lab experimental data of soil columns. It was validated by three field experiments and the relative errors ...
In 2001, a probabilistic safety assessment of the Radiation Monitor Calibration Laboratory of a Brazilian nuclear power station was performed to estimate its radiological risk. Owing to the lack of data, many conservative assumptions were considered. The purpose of this paper is to obtain the updated laboratory radiological risk. A human reliability analysis of the procedure for calibrating the ...
