Our compact, portable elemental analyzer utilizes nuclear magnetic resonance, which allows for rapid elemental analysis in complex mixtures such as food, brines, and other liquids. This NMR analyzer quickly measures sodium using a single calibration standard and is also portable, as it weighs less than 18 lbs.
Our portable NMR analyzer can quickly take any type of liquid and in less than a minute and accurately measure the concentration of a number of elements with absolutely no dilution or manipulation of the sample and without any consumable reagents.
This portable elemental analyzer uses magnetic resonance to directly quantify the content of specific elements in the sample. The signal response of each element is linear with the concentration. Therefore, the Turbospec 400 is easily calibrated using a single standard solution of a given element and can be calibrated in molarity, wt %, or ppm.
Magnetic resonance is highly specific unlike other methods such as atomic absorption spectroscopy which similar elements (e.g. Na, K) have similar absorption wavelengths and lack specificity.
Liquid and dispersions can be pipetted directly to a sample tube and analyzed. Solid matrices should be ground and extracted with water. It is not necessary to separate the solid and liquid components per se; this instrument measures the soluble sodium in virtually any matrix.
An NMR analyzer that has no moving or wearable parts means that routine maintenance is usually not necessary.
Since magnetic resonance’s response is linear to concentration, it is not necessary to use more than one standard. We recommend using a check standard in addition to the calibration standard for routine checks
This elemental analyzer has a 5 mm sample port. Standard economy or precision NMR tubes at least 100 mm (4 inches) in length can be cleaned and reused. Rinsing tubes with dilute acid are usually all that is required to keep tubes clean.
Many elements have isotopes which give NMR signals. For example, hydrogen, 1H is the mode sensitive stable isotope in the periodic table. Deuterium, 2H is also a stable isotope of hydrogen, but has a very low natural abundance at 0.0115 %. The third isotope of hydrogen, known as tritium, 3H is not stable but has a larger Larmor frequency than that of its abundant stable counterpart, 1H. This periodic table mock-up visually displays the elements which are most sensitive in orange. Elements which are somewhat less sensitive are in yellow and elements in blue are either very insensitive or do not have a stable isotope which has non-zero nuclear spin.
