Effervescent composition for improved carbon dioxide generation in insect monitor devices
View Patent ↗The present invention relates to a chemical composition and method of generating carbon dioxide for use with an insect monitor and/or capture device comprising: i) an effervescent agent; ii) a solid acid; iii) a deliquescent agent; and optionally iv) an anti-clumping agent.
1. A chemical composition for generating carbon dioxide for use with an insect monitor and/or capture device comprising:
i) an effervescent agent,
ii) a solid acid;
iii) a deliquescent agent which is magnesium chloride hexahydrate, and optionally
iv) an anti-clumping agent
wherein the molar ratio of the effervescent agent to solid acid to deliquescent agent is from 159:52:1 to 10:3:1.
2. The composition of claim 1 , wherein the effervescent agent comprises sodium bicarbonate.
3. The composition of claim 1 , wherein the solid acid comprises citric acid monohydrate.
4. The composition of claim 1 , wherein the anti-clumping agent comprises a material selected from the group consisting of fumed silica, amorphous silica, kaolin clay and mixtures thereof.
5. The composition of claim 1 , wherein the molar ratio of the effervescent agent to solid acid to deliquescent agent of from 40:13:1 to 20:6.5:1.
6. A chemical composition for generating carbon dioxide for use with an insect monitor and/or capture device comprising:
i) sodium bicarbonate,
ii) citric acid monohydrate;
iii) magnesium chloride hexahydrate, and optionally
iv) an anti-clumping agent
wherein the molar ratio of the sodium bicarbonate to citric acid monohydrate to magnesium chloride hexahydrate is from 159:52:1 to 10:3:1.
7. The composition of claim 6 , wherein the molar ratio of sodium bicarbonate to citric acid monohydrate to magnesium chloride hexahydrate is from 40:13:1 to 20:6.5:1.
8. The composition of claim 1 wherein the solid acid is malic acid.
