Hi. I am doing an assignment on forensic chemistry equipment. This is a section I have written "The infrared spectrometer is useful for identifying organic matter because it provides information about the molecules of a substance rather than only the atoms; however it gives only minimal elemental information about a sample." I am not really sure what is meant by 'elemental information'. Can anyone help? Also does anyone know how long the infrared spectrometer lasts and how much it costs? ty

I'm just your average college student but I donated what i could. I can't emphasize enough how helpful these videos are.

This should be what teaching is all about. empowerment through knowledge. not scamming people or trying to make money. Teachers don't make a lot of money but the right ones do make a hell of a difference in people's lives.

Thanks again. your ochem videos saved my butt last quarter.
