ikkegravimetriske

ikkegravimetriske refers to methods or techniques that do not rely on gravimetric (weight-based) measurements. The term is commonly used in geology, environmental science, and engineering to describe analytical approaches that determine composition, concentration, or physical properties through alternative means such as optical, electrical, magnetic, or acoustic signals. In geochemistry, for example, spectrophotometry, chromatography, or X-ray fluorescence can quantify elements in a sample without requiring mass loss or balance measurements, thereby offering faster, non-destructive analysis. In environmental monitoring, non-gravimetric sensors detect contaminants in water or air using electrical conductivity, electrochemical impedance, or laser-based spectroscopy, eliminating the need for laboratory-based gravimetric titration. In civil engineering, non-gravimetric techniques such as ground-penetrating radar, seismic refraction, or ultrasonic testing provide subsurface information about soil structure, rock layers, or structural integrity without direct density measurements. The advantage of ikkegravimetriske methods lies in speed, reduced sample preparation, and the ability to conduct in situ or continuous monitoring. However, these techniques may require calibration against gravimetric standards for absolute accuracy, and they often provide relative rather than absolute concentration values. The field continues to develop, with advances in sensor technology and data processing expanding the range of parameters that can be measured non-gravimetrically.
