Re: *BAP10* a purchase source (Worldwide?)

Very small concentrations are often expressed as ppm (parts per million)
e.g. Grams per million grams for a trace impurity in a solid.
For aqueous solutions this is the same as grams per million millilitres.
1,000,000/1,000

You should check for yourselves that:-
                 1 ppm = 1 mg per kilogram = 1 microgram per gram (solids)

                   1 ppm = 1 mg per litre = 1 microgram per ml (solutions)  =
.0001 grams per litre

5 grams of BAP costs around 35-40 dollors.

1 gram = 1,000 mg

1 gram per 1,000 litres = 1 ppm

1,000 ml = 1 liter

3,000 ppm =  3,000 mg per liter or 3 grams per liter.  = 3,000 grams per
1,000 litres = 3 grams per litre

12 dollars per liter of working strength BAP


If BAP 10 is a ten percent dilution then,
1ppm = 1 gram per 1,000 litres

100,000 ppm = 100,000 grams per 1,000 liters or 100 grams per liltre.

which would give you 33 litres of working strength BAP

OK so I was off on how expensive the BAP 10 is, but a person should not need
more than a litre or two.
Plus it's late and I cannot do math when I am tired.
