Paper accepted for publication entitled "Significance of previtamin D chromatographic resolution in the accurate determination of vitamin D3 by HPLC‑UV" to be published in the Journal of Food Compositional Analysis. This paper details chromatographic separation of vitamin D3 and the impact of previtamin isomerisation when using internal standardisation with vitamin D2.
Paper accepted for publication entitled "Significance of thermal isomerisation on the quantitation of total vitamin D3 in foods" to be published in Food Analytical Methods. This paper discusses the details the challenging aspects of vitamin D analysis due to differential thermal isomerisation.
At the 2018 Kudos Awards gala dinner, I was awarded the Hamilton City Council Emerging Scientist of the Year. It was great evening, fabulous meal and plenty of laughter with Te-Radar as MC.
I attended the 132nd AOAC Annual Meeting in Toronto.
I took opportunity to visit huge games workshop (boardgames and roleplaying games. My daughter calls these stores "Nerd Lairs", and since I am a nerd, I find them interesting places to visit. Also took a side-trip to see Niagara Falls which was worth the two-hour drive from Toronto.
A local newspaper, the Morrinsville News, has published a profile story of detailing my role at the Waitoa Dairy factory and appointment to the Official Methods Board of AOAC International.
Vitamin D method published as ISO standard—Geneva, Switzerland
An analytical method for vitamin D in infant formula I developed is now an ISO Standard and published as ISO 20636:2018 Infant Formula and Adult Nutritionals—Determination of Vitamin D by Liquid Chromatography-Mass Spectrometry. This vitamin D international standard will be proposed to Codex Alimentarius as a Type II 'dispute resolution' method, and it will become the reference method for vitamin D in infant formulas worldwide.
At the 39th session of the Codex Alimentarius Commission, recommendations by CCMAS were accepted and the vitamin D method I developed was officially adopted as a Codex Type II 'Reference Method' for dispute resolution and calibration purposes.
AOAC Official Methods Board appointment—Gaithersburg, MD, USA
I have just been appointed to the AOAC Official Methods Board (OMB). The OMB is the lead scientific committee which evaluates and approves official methods that can be used with confidence by regulated industry, regulatory agencies, contract research organizations and testing laboratories, and academic institutions. Official Methods undergo rigorous scientific scrutiny and demonstrate the highest level of confidence in a method. I am very excited by this appointment and am eager to begin my first 3‑year term which starts in August.
Laboratory visit—Lausanne, Switzerland
Visited a laboratory and discussed numerous analytical techniques and applications.
Stopped off at Bern and saw the Einstein Museum. I had a quick swim in Lake Geneva on a very hot day as I walked from Montreux to Château de Chillon.
Vendor visit—Glasgow, Scotland
Spent time learning about aflatoxin immunoassays.
Drove to see a couple of castles while in Scotland. Both Stirling and Edinburgh castles have stellar views, and I love touring castles.
