This review of laser ablation‐inductively coupled plasma‐mass spectrometry includes research that employed quadrupole instruments, and single‐collector and multicollector magnetic sector field instruments. The most important trend in 2004–2005 was the growing appreciation that small matrix effects in LA‐(MC)‐ICP‐MS need to be addressed in order to produce highly precise and accurate data by the method. The issue is most acute for isotope ratio measurements that require standard‐sample‐standard bracketing but can also be important for certain elemental analysis. Matrix‐dependent elemental and isotopic fractionations were studied from the standpoint of laser‐sample interactions and the behaviour of laser‐generated particles in the ablation cell, transfer tubing and ICP torch. Innovations in LA‐(MC)‐ICP‐MS involved signal smoothing, in torch laser ablation, on‐line isotope dilution and molecular oxide monitoring. Other important research was carried out on the calibration and homogeneity of various reference materials; and the exploration of mature ( in situ U‐Pb geochronology) and emerging (apatite fission‐track chronometry, U‐Th/He thermochronology, boron/strontium/uranium‐series isotopic microanalysis) applications in the Earth sciences.
