“…As an attractive alternative to conventional PN for highefficiency aqueous sample introduction, ultrasonic nebulization (USN) demonstrated the capability to achieve exceptionally high sensitivity with ICP-MS, 24,25 which has also been successfully employed in the determination of trace REEs in crude oil. 26 However, USN-ICP-MS also faces difficulties in residue rinse and sample consumption, leading to large moisture introduction.…”

“…To this purpose, the certification of the geographical origin of wine is growing in importance, because of the European regulations issued to protect the denomination of origin of agricultural products. Therefore, it is important to develop methods for the characterization of wines according to chemical parameters linked to the vine and territory origins, to get the Denomination of Controlled Origin trademark 1–4 . Piedmont is a region situated in the northwestern Italy and is renowned for the production of several wine types of excellent quality.…”

[1][2][3][4] Piedmont is a region situated in the northwestern Italy and is renowned for the production of several wine types of excellent quality. Apart from the most famous wines, such as Barolo, Barbaresco, and Barbera, the wine producers are nowadays addressing the growing attention on wine varietals less common, but that represent an important "cultural heritage" of the region because they are known from ancient times, but their production severely reduced in the past years.…”

Volatile components of Pelaverga red wines from Piedmont (Italy)

et al. 2023

Background: The characterization of a typical red wine from Piedmont (north-west Italy), Pelaverga, was performed by means of headspace solid phase microextraction coupled to gas chromatography-mass spectrometry. Two different kinds of Pelaverga are known, hystorical and Verduno, which differ with the area of production. The main volatile compounds of the wine were identified and semi-quantified. Principal components analysis (PCA) was performed to identify possible clusters among the different samples analyzed.Results: Forty-eight volatile compounds were unambiguously identified in the wines sampled. The two types of Pelaverga analyzed displayed a very similar volatile profile.The most abundant volatile compounds were two esters, ethyl octanoate and diethyl succinate, and two alcohols, isoamyl alcohol and ethyl phenyl alcohol. Few varietal compounds were detected, probably due to their low concentration; among these, we were not able to detect rotundone, which is reported to impart characteristic spicy notes to this kind of wine. Application of PCA did not allow to differentiate between the two types of Pelaverga on the basis of their volatile profile. Conclusion:The present work is, to the best of our knowledge, the first complete report about the volatile profile of Pelaverga wines and represents the first step of a research project aiming at characterizing food products from Piedmont on the basis of chemical parameters. Differentiation between the two types of Pelaverga will likely require the determination of different chemical parameters in conjunction with volatile compounds.

“…Ultrasonic nebulization (USN) has been proposed as an attractive alternative to PN for highly efficient aqueous sample introduction. , Recently, miniaturized ultrasonic nebulization (MUN) has received increasing attention and obtained various applications even in daily life, including humidifiers. − In 2020, it has also been used as an efficient sample introduction unit for a soft ionization source . It should be noted that MUN is an ultracheap (<$1) and easily available device and it can continuously convert the solution into aerosols based on the cavitation effect without peristaltic pumps or compressed gas.…”

Development of a Portable Method for Serum Lithium Measurement Based on Low-Cost Miniaturized Ultrasonic Nebulization Coupled with Atmospheric-Pressure Air-Sustained Discharge

An accurate, rapid but cheap, and portable method for monitoring of serum lithium (Li) is highly desirable for mental patients who take Li medicine for treatment. Conventional techniques are usually bulky, costly, and cannot provide on-site real-time measurements. Herein, a miniaturized, reliable, costeffective, and portable optical emission method for rapid and sensitive determination of serum Li was developed based on a combination of miniaturized ultrasonic nebulization (MUN) and a low-power (≈22 W) atmospheric-pressure air-sustained discharge (APAD) excitation source. The proposed method eliminates the use of any compressed gas or pump and can achieve serum Li detection within 40 s with low sample consumption (less than 20 μL serum). Except for dilution with water, no extra treatment is needed for serum Li analysis by MUN-APAD-OES. In addition, it offers a significant advantage of good tolerance to the coexisting high concentration of Na, K, Ca, and Mg, which is in contrast with the obvious matrix effect encountered in conventional inductively coupled plasma optical emission spectrometry (ICP-OES). Different operating parameters affecting the performance of MUN-APAD-OES were evaluated. Under optimized conditions, the detection limit of Li (670.8 nm) was calculated to be 0.6 μg L −1 (6 μg L −1 in serum). Finally, the accuracy of the proposed method was validated by the analysis of two certified reference materials (Seronorm serum L-1 and L-2 RUO), six real human serum samples, and eight real animal serum samples. All of the results indicate that the low-cost and low-power MUN-APAD-OES provides a promising reliable method for on-site serum Li measurement and may also be extended to other elements.
