Frequently Asked Questions (FAQs) About PPM
6. Your Burning Questions Answered
Still got questions about PPM? Don't worry, you're not alone! Here are some frequently asked questions to clear up any remaining confusion.
Q: Is a higher PPM always worse?
A: Not necessarily! It depends on the substance. For harmful substances like toxins, a higher PPM is definitely worse. But for beneficial substances like vitamins or minerals, a higher PPM might be desirable, within safe limits, of course.
Q: How do they measure PPM?
A: There are various analytical techniques used to measure PPM, depending on the substance being measured. These techniques include spectrophotometry, chromatography, and mass spectrometry. These methods are extremely sensitive and accurate, allowing for precise measurement of even trace amounts of substances.
Q: Can I measure PPM at home?
A: It depends on what you're trying to measure. There are some home testing kits available for things like water quality. However, these kits are generally less accurate than laboratory methods. For critical measurements, it's always best to rely on professional testing services.
Q: Why is PPM used instead of percentage all the time?
A: PPM is favoured for very low concentrations because percentages become cumbersome and involve many leading zeros. It is simpler to say 1 PPM than 0.0001%.
