To make GSD-10 you'll need a 1 liter mixing container, the constituent chemicals, and standard lab safety equipment, including; dust mask or respirator, lab glasses and gloves. Work in a well ventilated area.
GSD-10 is made up acording to standard lab practices. Start by adding 750ml of distilled water to your mixing container. Add with stirring, the constituent chemicals in the order they appear in the formula, and be sure each chemical is completely dissolved before adding the next. When all of the chemicals have been dissolved, top up to 1 liter with distilled water. Your concentrated stock solution is now ready to use. Dilute 1:10* to make a working solution.
* Dilution ratios are written in the form X:Y. X = stock solution, and Y = total solution volume. To make a 1:10 dilution, simply divide the total volume by 10 to find the correct volume of stock solution. V/10=VSS (volume divided by ten equals volume of stock solution)
To make 1 liter- 1000/10=100ml stock solution
To make 300ml- 300/10=30ml stock solution
