Abstract
Przedmiotem wynalazku jest sposób wyznaczania stezenia czasteczek w próbce, obejmujacy nastepujace kroki: a) podzial próbki na N rozdzielnych pod-objetosci, kazdej o objetosci vi, gdzie i jest indeksem pod-objetosci, przy czym albo próbke dzieli sie na pod-objetosci w sposób deterministyczny, to jest taki, w którym objetosci vi zadane sa przez ciag wartosci funkcji analitycznej f(i) lub przez predefiniowany zbiór wartosci, albo próbke dzieli sie na pod-objetosci w sposób losowy, to jest taki, by rozklad objetosci pod-objetosci byl zgodny z rozkladem prawdopodobienstwa P(v), to znaczy liczba pod-objetosci o objetosci vi w przedziale (v, v+?v) zadana jest wzorem: N?vv+?vP(v)dv; b) przeprowadzenie w kazdej tak uzyskanej pod-objetosci procesu wzmocnienia obecnosci co najmniej jednej wspomnianej czasteczki do mierzalnego sygnalu; c) pomiar wspomnianego sygnalu w kazdej pod-objetosci i przypisanie tej pod-objetosci parametru ki, przy czym parametr ki, przyjmuje wartosc 1, jezeli wynik wspomnianego pomiaru wskazuje na to, ze w danej pod-objetosci znajduje sie co najmniej jedna wspomniana czasteczka oraz 0 w przeciwnym wypadku, zas i jest numerem pod-objetosci; d) obliczenie sumy K = ?ki • wi(vi), gdzie i jest numerem pod-objetosci a suma przebiega po wszystkich pod-objetosciach na które zostala podzielona próbka i=1..N, zas wi(vi) jest waga, która moze zalezec od objetosci pod-objetosci; e) wyznaczenie estymaty E(C) stezenia wspomnianych czasteczek w próbce na podstawie wartosci K, N i {vi} lub P(v) za pomoca znanego algorytmu statystycznego opartego o formalizm Bayesa, charakteryzujacy sie tym, ze podzial próbki, o którym mowa w kroku a) obejmuje co najmniej dwie pod-objetosci o róznych objetosciach.The invention relates to a method for determining the concentration of particles in a sample, comprising the following steps: a) dividing the sample into N separate sub-volumes, each with the volume vi, where i is the index of the sub-volume, whereby either the sample is divided into sub-volumes in the manner deterministic, that is, one in which the volumes vi are given by the sequence of the values of the analytic function f (i) or by a predefined set of values, or the sample is divided into sub-volumes at random, i.e. consistent with the probability distribution P (v), that is, the number of sub-volumes with the volume vi in the interval (v, v + v) is given by the formula: N vv + vP (v) dv; b) performing in each sub-volume thus obtained a process of amplification of the presence of at least one said molecule for the measurable signal; c) measuring said signal in each sub-volume and assigning this sub-volume to the parameter ki, the parameter ki, being 1 if the result of said measurement indicates that there is at least one said molecule in a given sub-volume, and 0 otherwise, and i is the sub-volume number; d) calculation of the sum K =? ki • wi (vi), where i is the number of the sub-volume and the sum runs over all sub-volumes into which the sample was divided i = 1..N, while wi (vi) is the weight which may depend on the volume of the sub-volume; e) determination of the estimate E (C) of the concentration of the said molecules in the sample on the basis of the values of K, N and {vi} or P (v) using a well-known statistical algorithm based on the Bayesian formalism, characterized by the fact that the partition of the sample referred to in of step a) includes at least two sub-volumes with different volumes.
