Flame tests are used for metal ions in group 1 and 2

+ NaOH is for other metal ions

+ NaOH for ammonium ions

+ Acid for carbonates

+ AgNO3 for halides

+ BaCl for sulphates

+ NaOH for nitrates

Elements can be detected by 

* Atomic line spectroscopy
Mass spectroscopy

Compounds can be detected by
Infrared spectroscopy (identifys bonds)
* Ultraviolet spectroscopy (for nitrate and phosphorus ions in water)
* Nuclear magnetic resonance spectroscopy (detects organic molecules)
* Gas/liquid chromoatography
* Mass spectroscopy

I know its a lot, hope that helps
