Microplastics Calibration Standard-Low set (MPCS-L)
for MPs analysis using Py-GC/MS
The Microplastics (MPs) Calibration Standard (MPCS) is used to identify and quantify MPs using PyGC/MS. It allows the user to easily create calibration curves for quantification of MPs. Two MPCS withdifferent diluents (SiO2 or CaCO3) are available. Both MPCS contain a few µg each of commonly used 12
polymers which are homogeneously dispersed with a solid diluent for easy weighing on semimicrobalances. This product has a polymer concentration of approximately one-tenth of the MP Calibration
Standard set (Product No.: PY1-4940). Suitable for quantitative analysis of trace MP samples.

Selection of a MPCS from the two types of products
In most studies on Py-GC/MS analysis of environmental MPs,
MPs are extracted from various matrices. After pretreatment
processes, collected particles are put in a sample cup forpyrolysis. To enable easy weighing for the quantitative
analysis of MPs, use of fine particles (SiO2) as a diluent(Method-A) was reported, but PU showed unfavorable
pyrolytic behavior for quantification (Ref.1).
References

When CaCO3 was used as a diluent instead of SiO2, theproblem on PU quantification was eliminated due to the weakcatalytic activity of CaCO3 at a pyrolysis temperature of 600ºC (Method-B, Ref. 2). With the MPCS, two types of diluentsare available (A: MPs-SiO2 and B: MPs-CaCO3) so that one
can select either method-A or method-B depending on thetarget polymers.

Use of catalytic action of CaCO3 in the pyrolysis of polymers● Polyurethane (PU)One of major pyrolyzates of PU is methylenediphenyl diisocyanate ( e.g.,MDI). However, it is hard to quantitate PU using the MDI GC peak due tothe high reactivity of MDI. Therefore, the more stable pyrolyzate, diamine(MDA), is preferred for quantitation of PU. CaCO3, which has weakcatalytic activity, reacts with MDI to form MDA in the pyrolyzer.
