Load column crush

Steel reloading has a less forgiving reputation and certainly requires your full attention. Neither the shot nor the wad column crush or collapse to absorb excess pressure as will lead when too much of an ingredient, either shot or power, is used. In fact, barrel and chamber pressures tend to rise faster and higher from improper assembly of steel loads than lead. 

Procedure. A vitamin B complex tablet Is crushed and placed In a beaker with 20.00 mL of a 50% v/v methanol solution that Is 20 mM In sodium tetraborate and contains 100.0 ppm of o-ethoxybenzamIde. After mixing for 2 min to ensure that the B vitamins are dissolved, a 5.00-mL portion Is passed through a 0.45- xm filter to remove Insoluble binders. An approximately 4-nL sample Is loaded Into a 50- xm Internal diameter capillary column. For CZE the capillary column contains a 20 mM pH 9 sodium tetraborate/sodlum dIhydrogen phosphate buffer. For MEKC the buffer Is also 150 mM In sodium dodecylsulfate. A 40-kV/m electric field Is used to effect both the CZE and MEKC separations. 

Velocity of Detonation, 4511 m/sec at d 0.88 in column 0.22 diam 5100 m/sec at d 1.1 Initiating Action, The minimum amounts of HMTD required to detonate 0.4 g of the following HE were determined by increasing the. amounts of HMTD until the amount of sand crushed was at a maximum. (Explosives and initiator were loaded in No 8 cap at 1000 psi pressure)... 

Solid Support—The support for use in the packed column is usually crushed firebrick or diatomaceous earth. Sieve size will depend on the diameter of the column used and liquid-phase loading, and should be such as would give optimum resolution and analysis time. Optimum size ranges cannot be predicted on purely theoretical grounds. For some systems it has been found that a ratio of average particle diameter to column inside diameter of 1 25 will result in minimum retention time and minimum band widths.
