    Chemicals X-rays
AI Thread Summary
Customs x-ray security checks are not capable of detecting specific chemicals, including traces of toxic substances. While these machines are effective for identifying the presence of illegal drugs and certain contraband, they do not have the ability to analyze or identify specific chemical residues. Therefore, any concerns regarding the detection of toxic chemicals in products would require different testing methods beyond standard x-ray technology.

Could customs x-ray security check find out if there is trace of toxic chemical left in the product? I do NOT mean illegal drug because it
is supposed to be found out, but how about if there is any trace of other toxic chemicals? Could it be found out?

No, x-ray machines do not detect specific chemicals.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

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...

Thread 'Why does having 8 valence electrons make an element inert?'

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!!

Thread 'Resists for etching Aluminium with NaOH'

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...
