Metabolic profiling of human plasma and urine in chronic kidney disease by hydrophilic interaction liquid chromatography coupled with time-of-flight mass spectrometry : a pilot study [PDF]

, 2017
A typical characteristic of chronic kidney disease (CKD) is the progressive loss in renal function over a period of months or years with the concomitant accumulation of uremic retention solutes in the body.

Time-of-Flight Secondary Ion Mass Spectrometry Analysis of Hair from Archaeological Remains

European Journal of Mass Spectrometry, 2003
Hair from four individuals excavated from burial sites in Pacatnamu, Peru from the Moche (450–800 AD) and Lambayeque (900–1100 AD) periods was sectioned longitudinally and analysed with time-of-flight secondary ion mass spectrometry (ToF-SIMS). An attempt was made to distinguish biogenic and diagenetic contributions to the elemental concentrations in ...
