The phrase "a far higher concentration" is correct and usable in written English.
It can be used when comparing the levels of concentration of a substance or element in different contexts, such as scientific or analytical discussions.
Example: "The new formula resulted in a far higher concentration of active ingredients, leading to improved effectiveness."
Alternatives: "a significantly greater concentration" or "a much higher level of concentration."
The gel, which has a far higher concentration of chlorhexidine than used in the mouthwash, is heat stable and packaged in sachets that resemble ketchup packets used in fast food restaurants.
The response of WO3-dopedWO3-dopedn film was stronger to 500 ppm of NO2 than those of pristine TeO2 nanorods and TeO2-CuO nanorods to 10 ppm of NO2, but it should be noted that the former response was obtained to a far higher concentration of NO2.
This is in contrast to the protease inhibitors saquinavir and lopinavir, where the effect on p24 production occurs at a far higher concentration than the effect on viral replication.
The FMRFamide-related peptide FLRF-amide or FIRF-amide (581.3 Da) was also identified in stellate and optic lobe extracts, again with a far higher concentration in optic lobe extracts than in SG extracts (Fig. 4A,B).
As a case in point, inhaled antibiotics achieve far higher concentrations with far fewer side effects than orally delivered antibiotics [55, 62].
"The process of drying and pelletizing poultry manure concentrates the arsenic, so the end product has far higher concentrations than the starting manure levels have -- which are already very high," said Joshua Hamilton, senior scientist at the Marine Biological Laboratory in Woods Hole, Mass.
Much like blueberries, the skin of tomatoes contains far higher concentrations of phytonutrients than their flesh, meaning small cherry types contain far more than beefsteaks.
The concern now is that any further collapse in the reservoir walls would liberate industrial slurry with far higher concentrations of toxins.
But a draft report last year by the federal Environmental Protection Agency found that fly ash, a byproduct of the burning of coal to produce electricity, does contain significant amounts of carcinogens and retains the heavy metal present in coal in far higher concentrations.
Note that although DA concentrations were measured by microdialysis, our analysis purposefully focused mainly on the DA metabolite levels since these measures have proven to be much more consistent across the literature and they are expected to be more robust due to their far higher concentrations.
