The phrase "analyzed using a flame" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly when discussing methods of analysis that involve combustion or flame-based techniques.
Example: "The sample was analyzed using a flame to determine its elemental composition."
Alternatives: "examined with a flame" or "assessed through flame analysis".
Na and K were analyzed using a flame photometer.
Concentrations of K were analyzed using a flame photometer and P was analyzed using the colorimetric method with molybdenum blue and ascorbic acid as the reducing agents.
Heavy metals (Cd, Cr, Cu, Fe, Mn, Pb, and Zn) in the sediment samples were analyzed using a flame atomic absorption spectrophotometer (Shimadzu AA-670, Kyoto, Japan).
An aliquot of each sample was analyzed using a zinc flame or graphite atomic absorption spectrophotometer Z-81000, HiTokyo, Japan, Japan).
Methane concentrations in the outflow of the methane surrogate tests were analyzed using a gas chromatography flame ionization detection (GC-FID) method (USEPA method RSK-175), which has a detection limit of 10 µg/L (USEPA 2004).
The total petroleum hydrocarbons (TPHs) were analyzed using a gas chromatograph with a flame ionization detector (GC-FID).
The asymptotic structure of laminar, moderately rich, premixed methane flames is analyzed using a reduced chemical-kinetic mechanism comprising four global reactions.
Samples were analyzed using a Perkin Elmer (Boston, MA, USA) 8500 GC with a Flame Ionization Detector (FID) and a Hewlett Packard Agilent Technologiess, Palo Alto, CA, USA) 6890 Series GC System with a 5973 Mass Selective Detector equipped with an Agilent 7683 Series Injector.
