    Analysis budget
AI Thread Summary
The discussion centers on the need for budget estimates for geochemical analysis of water and sediments, specifically focusing on the costs per sample for Tributyltin Oxide (TBT), Per- and Polyfluorinated Alkyl Substances (PFAS), and Pesticides. The original poster, Roberto da Silva, is seeking information on the individual costs of these analyses and resources for updated pricing in Europe and the USA. The conversation highlights the importance of obtaining accurate budget information for these specific environmental contaminants to aid in the preparation of a report.

TL;DR Summary
Does anyone know, or can anyone point me where can I check out budgets for TBT, PFAS and Pesticides analysis on soil/sediment samples?
I need to do a brief report, introducing geochemical analysis on water and sediments, and its asked for Budgets (per sample) for analysis on Tributyltin Oxide (TBT), Per- and Polyfluorinated Alkyl Substances (PFAS) and Pesticides. Does anyone know how much those three would cost individually (per sample)? Or where can I check for updated budgets in Europe or USA?
I appreciate any help given on this subject.
Thanks,

Roberto da Silva

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
