In this review and comment on the most important advances published in X-ray fluorescence (XRF), atomic absorption spectrometry (AAS) and neutron activation analy sis (NA A) for 2004 and 2005, a baseline assumption is that the level of activity in terms of new advances is anticipated to be low because these techniques are considered "mature". These individual totals are comparable to all other significant analytical techniques except plasma mass spectrometry, which produced significantly more data.

X-ray fluorescence spectrometryIn this field, the outstanding technical feat that must be noted is the development of a portable synchrotron (Yamada et al 2004). In 2004, some 3% of all papers were devoted to XRF spectrometry (10/309), rising to 4.9% in 2005 (16/325).

“…In this field, the outstanding technical feat that must be noted is the development of a portable synchrotron (Yamada et al 2004). The achievement of these authors has been to construct a 20 MeV radiation source of 1.2 m external-diameter with a 0.15 m orbital radius, which can be transported in the back of a small truck.…”

These technologically mature techniques occupied a stable to modestly increasing sector of the spectrum of analytical methods in Earth and environmental sciences in 2004–5. Despite this, several notable advances were reported in this two year period. In the field of X‐ray fluorescence spectrometry, these included the development of portable synchrotron and total reflection instruments, the use of pyroelectric crystals as X‐ray generators, introduction of high‐purity Ge detector arrays, and the development of an XRF imaging spectrometer with the capability of mapping analytes and X‐ray intensity ratio. Atomic absorption s spectrometry saw major work published on high‐resolution continuum source AAS (HR‐CS AAS) involving the development of a xenon short‐arc lamp. Other advances included the use of laser wave mixing in a graphite furnace tube (with a claimed detection limit of 10–16 g g‐1), solid sampling and ultrasound in sample preparation. Neutron activation analysis saw two innovations that may herald future growth in this technique, namely a neutron source free of a nuclear reactor and a detector operating at room temperature.

“…Although possibly stretching the definition of 'portable', two PXRF-related developments that fall into the category of 'astonishing' are available for review this year. The first was a paper by Yamada and colleagues, 205 who reported the analysis of heavy elements (such as Ag, Pb, Pt, Sn and W from the respective K-lines), using a portable synchrotron excitation source (named MIRRORCLE-20). The portable synchrotron comprised a single piece of normal conducting magnet of 1.2 m outside diameter and 0.15 m orbit radius.…”
