Inorganic substance assay can be find out by dissolving it in HCl.Take 2gm substance in a crucible and add 20ml 10% HCl and boil for 2 min. Cool and filter it through ash less whatman filter paper.Wash the residue by distilled water.Place the filter paper in pre weighed crucible and place it in muffle furnace at 800*c for 2 hrs. cool and weigh the crucible and calculate the assay.

You could measure the volume of fuel in the tank by weighing the tank accurately as it is filled with fuel. The weight of a gallon of fuel is known accurately. Home heating oil tanks utilize crude floats to measure the height of the oil level in the tank, but more sophisticated level indicators are available for industrial uses.\nSearch http://www.ThomasNet.com for that application.\nhttp://www.thomasnet.com/nsearch.html?cov=NA&which=prod&what=tank+level+sensors&navsec=search&heading=96118542

Here you have a free downloable PDF presentation from the 28 Sep 05 Conference Micro & Nano Technology (MNT) Measurement Club. I think it's worth to have a look.\n\n"Measuring Nanoparticle Surface Area and Porosity by Gas Sorption"\nMike Tucker, Quantachrome UK\nThe technique of gas sorption has long been used for the determination of surface area and pore size distribution of particulate systems and porous solids. While traditional sorption systems have proved adequate for the majority of tasks, the latest generation of ultra-fine materials, often coupled with microporosity offer new challenges to the sorption scientist. To meet these challenges many new developments have been made in the fields of analytical instrumentation and software modelling. The presentation will review some of the new techniques available, and provide examples to illustrate their applicability to the field of nanotechnology.\nDownload presentation: http://www.npl.co.uk/php/docs/download.php?area=metrology_clubs&path_name=/metrology_clubs/mnt/meetings/28sep05/presentations/connagh.pdf

Take a spray bottle, add a small amount of dish soap and fill with water.  Spray the surface down and look for the bubbling.  Or you could take it to a pool or lake and do it that way.  Obviously the air mattress must be full of air first.  LOL.

hi, \n\nacetone will do the job nicely.\n\nbe careful, though, it essentially is making napalm.\n\nhere is a list of the effects of variuos solvents, though i think it's on bulk polyurethane, not the foam:\nhttp://www.rimnetics.com/rimsolventsheet.htm\n\nanything there that says breaking, collapse or degradation would probably eat the foam up.\n\ncheers!

Put the stones in a container partly filled with water. Mark the before and after levels. Then measure the volume of the amount of water it takes to fill up from the low line to the high mark. This

The dyes added to shampoos are usually only there at VERY low levels (typically less than 0.001%). When the shampoo foams, internal light reflection within the bubbles further reduces the apparent dye colour.\n\nIt is possible to produce coloured foams but the dye load needs to be increased dramatically (up to about 0.05%). The problem with this is there is then enough dye in the shampoo to actually stain. This level of dye is actually used in some high foam CAR shampoos because customers think that the colour strength is somehow related to the detergent strength (WRONG!).\n\nYou can also play some neat tricks with fluorescent dyes and optical brighteners - which activate ONLY when struck by UV light and so may be light in colour in the shampoo but higher in colour as they catch more light when dilute.
