What's the difference between gravimeter and gravimetric?
Gravimeter
Definition:
(n.) An instrument for ascertaining the specific gravity of bodies.
Example Sentences:
(1) Therefore concentration of these two fractions has to be systematically measured.--The paper presents a dust gravimeter--new in its structural composition--suitable for measuring concentration of the two fractions simultaneously and separately.
(2) Using a gravimeter, body sway studied in 26 chronic schizophrenic patients, 10 schizoaffective disorder patients and 21 normal subjects.
Gravimetric
Definition:
(a.) Of or pertaining to measurement by weight; measured by weight.
Example Sentences:
(1) Quantity of water in the lung (Qwl) was also measured by gravimetric method.
(2) The gravimetric or loss-on-drying method is no longer listed as the required method; the 1.0% moisture limit is no longer specifically stated in the regulation.
(3) We used a gravimetric method to determine the ratio (gamma) of pulmonary venous to total pulmonary vascular resistance in intact dog lungs.
(4) The 3 gravimetric assays (oven-drying, freeze-drying or freeze-drying as well as oven-drying) had a very high precision (coefficients of variation (CV) 0.2-0.4%) and were easy to perform.
(5) We measured CO2 production using the Haldane gravimetric technique and compared these values with estimates derived from isotopic data.
(6) Dust was measured by the gravimetric method according to the Finnish standard.
(7) Gravimetric and histological studies of lymphoreticular tissues during growth of a syngeneic squamous cell carcinoma in Wistar rats show that the regional lymph node anergy reported previously in this system is associated with replacement of paracortical small lymphocytes by large blastoid cells.
(8) EVLW was determined gravimetrically at 6 hr to confirm the final double indicator dilution values.
(9) Determination of fungal elastase, however, requires partial purification of culture extracts and the orcein elastin or gravimetric method.
(10) The ratio of the extravascular lung water measured in this way to that measured gravimetrically also increased, to reach an asymptotic proportion of close to 100%.
(11) The injection of plasma, saline, or erythrocyte (RBC) concentrate into the pulmonary circulation produces a change in the gravimetric density of the blood outflow similar to the dilution curve of dye.
(12) A gravimetric plethysmograph, the technique of its use and its evaluation in vascular surgical practice are described.
(13) To test the method a regression equation was developed using the 40K counts and body weight of young adult rats weighing 333-788 g; the results were compared with those obtained from the gravimetric determination of fat in the carcass.
(14) The gravimetric density was determined for both left and right lungs by averaging the CT numerical data within lung slices traced on a magnified video image of the thorax.
(15) On a gravimetric basis, dermatan and heparan were 10 fold less hemorrhagic than heparin.
(16) Total blood volume in an isolated organ system decreases and is manifested as a decrease in volume (plethysmographic) or weight (gravimetric).
(17) The line of best fit of the relative standard deviation between-laboratories (RSDR) plotted against the negative logarithm of the fractional concentration, C, extends from 1.2 and 1.0% for the gravimetric and titrimetric methods, respectively, at 100% concentration to 2.2 and 2.8% at 1.0% concentration.
(18) Gravimetric changes found in the thymus and the spleen suggest that the thymus plays an essential role until death in a tumor-bearing host and that the thymus and the spleen have inverse functions in relation to tumor growth.
(19) The time course of pulmonary congestion and pulmonary edema was examined using a gravimetric method in 19 open-chest anesthetized dogs.
(20) The advantages of the titrimetric method include simplicity, rapidity, convenience, sensitivity, reproducibility and specificity, whereas the gravimetric method is tedious and time-consuming.
