What effect does gaseous flow rate have on flame photometry?
Flame stability can be affected by a number of different factors when using a flame photometer. But today we ask about the effect gaseous...
Enthalpy and thermodynamics
We touched upon the subject of thermodynamics and entropy in a previous blog post, this week will continue the topic of thermodynamics...
How does a flame photometer work?
The flame photometer is a relatively low-cost, rapid and accurate analytical device used to determine the presence and concentration of...
What is a chemical reaction and why do they occur?
What may be a simple question can have chemists discussing its definition in detail for days, and the reactions driving force can add...
What is the difference between a laser and a maser?
We’ve all heard of a laser, but what about a maser? What is the difference between the two? Laser is an abbreviation of Light...
Reproducibility and the key role it plays in the scientific method
When it comes to setting up an experiment, proper planning is crucial. But what is the key role that it plays? All too often, people will...
Basic Mass and Moles chemistry equations in flame photometry
Basic Mass and Moles chemistry equations in flame photometry The equation between Mass and Moles is probably one of the most important...
60 years of the laser - from first invention to modern techniques
Lasers have certainly come a long way since the basic chromium-doped ruby examples were invented in 1960. 60 years, this small beam of...
What is compound formation interference in flame photometry?
Compound formation is a type of interference that occurs due to the elevated temperatures present in the flame. The threshold for some...
What is representative sampling and how can it be used on two-dimensional areas?
Representative sampling is a term analytical chemists use as a statistical basis for collecting samples from large sample sources that...
Identifying background radiation sources in flame photometry
Sources of background interferences are those that emit either light or electronic interference. These are usually cancelled out from the...
What is lattice energy and how does it influence flame photometry?
Lattice energy is the energy needed to separate a mole of an ionic solid into gaseous ions. Its internationally recognised definition is...
Can I use a phase diagram to determine states of matter?
When it comes to physics, a state of matter is one of the distinct forms in which matter exists. It’s understandable that you...
The scientific method – from conjecture and hypothesis to predictions and analysis
Having the ability to question what is all around us, is vital to our progression as the alpha species on Planet Earth. But how did we go...
What is spectral interference, when does it occur and how can it be minimised?
Spectral interference, or spectral overlap, is a term used by scientists who are interested in looking at the emission wavelengths of...
What is the difference between a covalent bond and a dative bond?
Today we discuss the difference between the two bonds. A covalent bond is a type of bonding which occurs between two atomic nuclei. This...
What is the visible light spectrum and can the human eye see it?
