Sequip has made the experience that we can save our clients a non negligible amount of cost and time if we get as much answers as possible for the accompaning circumstances of your future application / implementation of Sequip in situ systems for PAT, under your special conditions.
More than 4000 different products have already been measured successfully by Sequip for our customers!
In order to ease up the assessment of our questionnair we divided it into 5 sections in which the different questions are classified. These are:
- Motive driven aspects
- Applicational aspects
- Sensor depending aspects
- Electronics and software depending aspects
- Special requests

*Some of the questions may appear repeatedly in different sections. This is due to ..their correlation to the topic of the corresponding section.
1.1 What objective is to be achieved withthe measurement?
1.2 What is your biggest interest: to
detect fine - middle or coarse
fraction shifts?
1.3 What do you consider as the
absolute necessary resolution?
1.4 What is the really necessary min/max
dynamic measuring range
1.5 How many months do you expect
should remain between two
maintenance intervals?
1.6 What is the targeted date of
installation of the measurement
system
1.7 Would it be interesting to you to
reduce the price by a delivery time
extension?
Section 2

dispersions: how much residual
moisture is left inside %?
2. 3 What are the colors of the carrying
and the disperse phase?
2. 4 What is the color/opacity of the
particles:
under dry condition
dispersed in liquid
2. 5Are the particles visible under the
microscope in dry and/or wet
condition?
2. 6Are there air bubbles under
measuring condition? If yes, what
could be the approximate size?
(direct influence on the reflective behavior of the
laser beam - possibility to filter out)
2. 7Is the measurement intended for
batch or continuous process?
2. 8What is the relation of fine to
coarse material in %ige?
2. 9What is the relative/absolute portion
of fine particles of <100nm size in
%ige
2.10 What is the really necessary
min/maxdynamic measuring
range?
2.11On how many mounting points
would you like to perform in situ
measurement:
simultaneously during one
measurement lapse of time?
as a total for the complete
project?
2.12 After how many seconds/minutes/
hours do you need a new re-
freshed measurement update?
2.13 How long do you consider one
measurement cycle to continue?
2.14 What number of different particulate
elements (droplets, needles, cubes,
spheres, algues, bacteria’s, etc.)
does the formulation contain you
would like to be measured?
2.15 What are (is) the dimension(s) or
volume of the reactor/pipeline
Section 3
3. 1 Are the particles visible under themicroscope in dry and/or wet
condition?
3. 2 Are the droplets visible under the
microscope?
3. 3 How do the particles look like: ie.
spherical, longish, cubic, cone-
shaped, needle-like or different?
(important for determination of length, surface and/or
volume weighting)
3. 4 Do you already have pictures taken
of a. m. particles/droplets; either
with microscopic and/or in situ video
examination / measurement?
3. 5 In case your answer to 3.4 is yes: is
is it possible to make those pictures
confidentially available to Sequip?

soft or rigid agglomerates
during the process?

particle of your agglomerated
structure

or causing electrostatic charges at
any times?

necessary? Please also refer to
item no. 4.9 up to 4.15
