Dear Dr Marsden
Application for Senior Laboratory Technician
I am applying for the Senior Laboratory Technician post in your inorganic chemistry team. I have worked at Don Valley Analytical for six years, two as an apprentice and four as a technician in its accredited water testing laboratory.
I prepare about 250 drinking water and waste water samples a week and run them for metals and nutrients by ICP-MS and discrete analyser, checking every batch against its quality control samples. I make up our standards and calibration solutions and log each one so any result can be traced back.
I also look after six of our instruments. Planning the ICP-MS servicing cut its downtime from nine days a year to three. Your advert says the senior technician will help validate new methods, which is the work I want to do next, alongside my application to become a Registered Science Technician.
My CV is attached. I can join the weekend rota, and I would be glad to show you how I run a batch. Thank you for considering my application.
Yours sincerely
Kofi Asante
