The N2O gases are used for production of  Integrated circuit device,IC card, LED, LCD,microelectronics and photovoltaic as well as other industries; It mostly used by electronics factory for making screen of mobile or other electronics products. 
For medical use, it is a Surgical anaesthetic, widely used at hospital or clinic . For food grade use, It is an excellent food preservative, non-toxic, harmless and pollution-free, the milk dissolved with  laughing gas can keep fresh for a long time without refrigeration, so it is widely used at coffee shop.
