To "detect" something means to find it or discover that it is present somewhere by using equipment or making an investigation.
所以如果你想表達的是用儀器等to check the leakage of gas，就可以用to detect gas leakage，意思是找出是否有瓦斯洩現象。
If you "inspect" something, you look at every part of it carefully in order to find out about it or check that it is alright.
如果你想表達的是看看瓦斯器具是否損壞，則可以用to "inspect" the gas apparatuses
