Amplios conocimientos en el mundo de las partículas más pequeñas

La medición móvil de nanopartículas con el testo DiSCmini eleva sus posibilidades de medición a un nuevo nivel.

En el lugar de trabajo, en el tráfico, al encender la cale-

facción e incluso en salas blancas. Prácticamente, las

nanopartículas están presentes en todas las áreas y son

decisivas para la carga sanitaria, la protección medioam-

biental y el éxito de la producción. Además del gran signi-

ficado de las partículas más diminutas, con frecuencia se

han evitado las mediciones exhaustivas debido al tamaño y

la complejidad de los instrumentos de medición.

Con nuestro instrumento de medición de nanopartículas

portátil testo DiSCmini hacemos posible una medición

sencilla, en cualquier lugar y solo presionando un botón. El

dispositivo compacto registra la cantidad de partículas, el

diámetro modal y la superficie activa (LDSA) con una resolu-

ción temporal de solo un segundo. Además, no es sensible

a las vibraciones, es independiente de la ubicación y fun-

ciona sin sustancias de servicio.

ción en la medicina, las ciencias laborales y ambien-

tales así como diversos campos de investigación.

Además le brinda apoyo

• Para la valoración de la exposición personal

• Para la comprobación de la protección laboral y de

la salud

• Para la supervisión del aire ambiente

• Para el control del rendimiento de otros instrumen-

tos

Por cierto, el significado de un instrumento de medición se

reconoce no solo por los interrogantes que resuelve, sino

también gracias a las personas que lo utilizan. En las pági-

nas siguientes hemos reunido para usted más de 110 Abs-

tractos de publicaciones científicas. Aquí no solo obtendrá

información sobre la versatilidad con la que se puede usar el

testo DiSCmini, también podrá constatar que nuestro com-

pacto contador de nanopartículas ya se ha convertido en un

importante instrumento de medición estándar.

¡Le deseamos una lectura interesante!

a b s t r a c t

Real-time exposure measurements to nano-sized particles may result in large amounts of

time series data on particle size and total number concentration. Analysis of the particle

size distribution have thus far been limited to either graphical analysis of the distribution

over time or an evaluation of the mode over time. For large time series data, graphical

analysis of distributions is complicated and an assessment of the mode ignores the

important aspect of the variance in particle size. A statistical method of analysis is

proposed that overcomes those problems, based on a multilevel modeling approach and

assuming a lognormal model for the particle size distribution. Two empirical examples

illustrate the advantages of the proposed model, showing that useful summaries and

inferences can be obtained, even for large data sets. The model thus provides a tool for

practitioners to deal with large amounts of particle size distribution data obtained from

real-time nano measurement devices.

1. Introduction

Because of the increasing number of workers involved with nanotechnology and the potential health effects of working

with these nanomaterials, assessment of the exposure of workers to (manufactured) nano particles or more specifically

nanoobjects and their agglomerates and aggregates (NOAA), (ISO 2012) at the workplace receives considerable attention. To

locate sources of emission and to characterize different work situations in order to gain knowledge on exposure and how to

reduce l exposure levels, workplace aerosol measurements are performed. Because the size and associated surface area of

the particles in the (workroom) air is one of the most important parameters for studying manufactured nano particles with

respect to potential risk, most sampling methods for measuring nano-sized particles focus on both particle number

concentration and particle size distribution (PSD) using real-time size, resolved devices, e.g. Scanning Mobility Particle Sizer

(SMPS), Electrical Low Pressure Impactor (ELPI), Aerodynamic Particle Sizer (APS), etc.) rather than on the total particle

number concentration in a certain size range alone (e.g. optical counters like the Condensation Particle Counter (CPC), and

diffusion charging based devices like DiscMini, Nanotracer, etc.).

However, little attention has been paid on how to (statistically) analyze and report these measurement results. Both

particle number concentration and PSD have been studied using graphical methods (Brouwer et al., 2004; Demou et al.,

2008; Evans et al., 2010; Bekker et al., 2014). Although the authors showed that useful information could be retrieved,

graphical analysis is limited to making qualitative inferences. Quantitative analyses have often been limited to averages or,
