Indications and contraindications for arterial line insertion

Broadly, the indications for arterial line insertion are haemodynamic monitoring, continuous cardiac output monitoring, blood sampling or some intra-arterial diagnostic or therapeutic procedure (eg. endovascular stenting). Contraindications to arterial line insertion are largely factors which increase the risk of infectious or ischaemic complications to the point where it exceeds the benefit ...

What are 'clumped isotopes'? | Carbonate Research

The field of clumped isotopes is concerned with measuring an isotopologue of CO 2 gas with a mass of 47, i.e. where the two "heavy" rare isotopes ( 13 C and 18 O) are substituted in the CO 2 molecule. This is representative of the amount of "clumping" of the heavy isotopes in the crystal lattice of the carbonate measure.

FTIR Spectroscopy Basics | Thermo Fisher Scientific - US

FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular 'fingerprint' of the sample.
