Semen detection system and method

A system for detecting the presence of semen on material such as fabric, comprising:

• a solution of sodium phosphate, maleic acid, dye salt, naphthyl acid phosphate and water;
• a solution dispenser;
• and
• absorbent paper.

A method for detecting the presence of semen on a material, the method comprising:

• wetting an absorbent paper;
• blotting the suspected semen area with the wetted absorbent paper so as to transfer semen on the material to the absorbent paper;
• allowing the absorbent paper to dry;
• and
• applying a semen detection solution to the absorbent paper.

A method for detecting the presence of semen on a material, the method comprising:

• wetting a suspected semen area on the material;
• blotting the suspected semen area with an absorbent paper so as to transfer moisture from the wetted suspected semen area on the material to the absorbent paper;
• allowing the absorbent paper to dry;
• and
• applying a semen detection solution to the absorbent paper.

A method for detecting the presence of semen on material using a semen detection solution consisting essentially of sodium phosphate, maleic acid, dye salt, naphthyl acid phosphate and water, comprising:

• blotting the suspected semen area with absorbent paper so as to transfer semen on the material to the absorbent paper;
• drying the absorbent paper;
• applying semen detection solution to the absorbent paper at the location of the transferred suspected stain or stain area;
• and
• if the absorbent paper changes color within a waiting period after application of the semen detection solution, concluding that semen was present on the material.
