New ISFET pH meter PCE-ISFET

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 ...

A mathematical model to estimate errors associated with closed flux chambers

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 ...

Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

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 ...

Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

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 ...

Comparison of field and laboratory collected midwave and longwave infrared emissivity spectra / data reduction techniques

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, ...
