Partica CENTRIFUGE

Analyseur de nanoparticules à centrifugation

Mesure granulométrique haute résolution par centrifugation.

Avec une plage de mesure comprise entre 10 nm et 40 μm, l'analyseur Partica CENTRIFUGE CN-300 exerce une force centrifuge pouvant atteindre 30 000 G et utilise le contrôle de la température pour générer des résultats de mesure précis pour toute une gamme d'échantillons.

Développé d'après les retours des clients et en améliorant les technologies HORIBA existantes et nouvelles, cet analyseur est à la fois sûr et fiable tout en étant facile à utiliser.

Segment: Scientific
Fabricant: HORIBA, Ltd.

Mesure précise de la granulométrie pour les échantillons non dilués et dilués
Le principal atout de la centrifugation est qu'elle permet de mesurer la granulométrie après avoir classé les particules par taille. Un large éventail de résultats de haute précision peut ainsi être obtenu à partir d'une seule analyse. L'analyseur Partica CENTRIFUGE vous permet d'utiliser deux techniques de mesure : « Line-start mode » et « Homogeneous mode ».

Détectez les particules étrangères ou les agglomérations en faible quantité
Grâce à sa haute résolution, Partica CENTRIFUGE peut détecter les petites quantités de particules étrangères. Cet instrument génère des résultats de mesure fiables sur toute la plage de la distribution granulométrique, y compris pour les petites populations et dans la partie basse de la distribution.

Mesure stable même pour les mesures de longue durée
La fonction de refroidissement de la chambre à échantillon et du rotor empêche l'augmentation de la température de la fraction d'échantillon pendant la rotation, ce qui améliore la fiabilité des résultats de mesure en maintenant la viscosité constante. L'analyseur Partica CENTRIFUGE est conçu pour assurer un fonctionnement plus silencieux, plus simple et plus sûr.

Robuste et facile à utiliser

  • Fonctionnement simple et sûr : il suffit de placer une cellule remplie d'échantillon sur un rotor
  • La cellule de type cuvette est facile à nettoyer et à remplacer, ce qui réduit le risque de contamination
  • Conforme aux normes de sécurité internationales (CEI 6101-1/2-020)
     

Exemples de mesures

Mesure de distribution granulométrique haute résolution

La mesure d'un échantillon mixte contenant quatre types de particules de silice standard en concentrations égales a permis d'obtenir quatre types de distributions présentant quasiment la même surface. La mesure « Line-start mode » permet d'obtenir une distribution granulométrique précise, car les particules sont classées par la force centrifuge.

Échantillon : particules standard (mélange d'une goutte de chacune des particules de 0,48 μm, 0,73 μm, 0,99 μm et 1,57 μm)
Quantité d'échantillon : 10 µL
Solvant : solution aqueuse de saccharose
Condition de mesure : « Line-start mode »

Mesure de la distribution granulométrique d'une petite quantité d'échantillon à forte concentration

Exemple de pigment noir utilisé pour les imprimantes à jet d'encre à partir d'une solution non diluée. La distribution granulométrique d'un échantillon à forte concentration, qui est difficile à mesurer, est présentée avec une grande précision à partir d'un petit échantillon de 2 μL

Échantillon : pigment noir pour imprimantes à jet d'encre (solution non diluée)
Quantité d'échantillon : 2 µL
Solvant : solution aqueuse de saccharose
Condition de mesure : « Line-start mode »

Evaluation of Diameter (Thickness) and Aggregation/Dissociation State of Carbon Nanotube Dispersions
Evaluation of Diameter (Thickness) and Aggregation/Dissociation State of Carbon Nanotube Dispersions
Carbon nanotubes (CNTs) are thin, light, and flexible string-like materials that are composed entirely of carbon atoms. CNTs easily aggregate, so it is essential to understand and control the state of aggregation in order to achieve the expected performance. For this purpose, an analytical method that can quickly evaluate wide particle size distributions (PSD) from isolated dispersion to aggregation, with high resolution, is necessary.

Analysis to Separate Mixed Samples of the Same Size but Different Materials
In general particle size analyzers, particles of the same size are measured as the same size regardless of material, making it difficult to separate particles of different materials when they are mixed together. The centrifugal sedimentation particle size analyzer measures the sedimentation speed and converts it into a particle size value using the density information of the particles. Therefore, particles of the same size but different densities will have different settling speed and can be measured separately.

Chemical Mechanical Polishing (CMP) technology is used as an indispensable fundamental technology in the manufacturing process of ultra-large-scale semiconductor integrated circuits (ULSI). CMP is a technique in which the surface of a substrate is softened, removed or flattened by chemical etching and frictional abrasion with a chemical slurry that contains abrasive particles. Fumed silica abrasive particles are synthesized in a gas phase reaction in flame and are dispersed as secondary particles that are aggregates of primary particles. They are known to have thiogenic properties. Although the rate of polishing is high for fumed silica, its polishing precision is inferior to that of colloidal silica.

Nanocellulose is a fibrous substance derived from wood and is attracting attention as a cutting-edge material. Cellulose nanofibers (CNF) manufactured by TEMPO oxidation are cellulose fibers that have added carboxy groups at high density. This type of CNF is made with high efficiency and is characterized by a very thin and uniform fiber width of about 3 nm. To utilize nanocellulose, it is important to understand the fiber diameter and dispersion state. To do so, it is necessary to have an analytical method that can quickly evaluate a wide ranges of particle size distribution, from well-dispersed particles to agglomerates at high resolution.
