Laboratory and Field

Crude oil quality is determined by its chemical composition, and two components stand out as particularly influential: asphaltenes and vanadium complexes. Asphaltenes are the heaviest fraction of crude oil, consisting of polyaromatic cores with aliphatic side chains and trace metals. Even in small concentrations they tend to aggregate, increasing viscosity, plugging pipelines, and deactivating catalysts during refining. Vanadium, often present as vanadyl porphyrins, is a known catalyst poison and a geochemical fingerprint of oil origin and degradation. Because these fractions directly impact flow assurance, refining efficiency, and ultimately crude oil value, accurate monitoring is essential. Why ESR? A Direct Window into...

Explore the Power of the ESR5000
From radiation dosimetry to environmental research and pharmaceutical quality control, the ESR5000 delivers high-sensitivity ESR/EPR analysis in a compact benchtop format. Discover real-world applications across chemistry, life sciences, and beyond.

Benchtop NMR has evolved dramatically in recent years and Bruker’s Fourier 80 sits at the forefront of this transformation. Launched in 2019 and widely adopted since, this 80 MHz proton (¹H) FT‑NMR system delivers impressive resolution and flexibility while fitting seamlessly into standard lab environments. Why the Fourier 80 Stands Out Cryogen‑free, no extra infrastructure: Runs on a permanent magnet; no liquid helium/nitrogen or water cooling needed. It can sit in a fume hood or on a bench and requires minimal setup. High resolution & sensitivity: Offers excellent lineshape (<0.4 Hz standard, down to 0.3 Hz with HD-option) and strong sensitivity (≥240:1 for ¹H-only, ≥180:1 for...
