Closure of the courtroom was justified by the undercover officer's Hinton hearing testimony that he had been engaged in some 150 drug operations in the vicinity of defendant's arrest, that some of those cases were still pending in the courthouse where defendant was being tried, and that he was now temporarily engaged in undercover work in another neighborhood but expected to be re-transferred to the vicinity of defendant's arrest shortly, all of which established the necessary spatial and temporal relationship among the courthouse, the location of defendant's arrest, and the anticipated geographic location of the undercover officer's future investigative work (see, People v Martinez, 82 N.Y.2d 436, 440-441, 443; see also, People v Badillo, 207 A.D.2d 742; People v Torres, 204 A.D.2d 131, lv denied 84 N.Y.2d 833; People v Ayala, 202 A.D.2d 262, lv denied 83 N.Y.2d 908). The closure was limited and, under the facts of this case, there were no reasonable alternatives.
Viewing the evidence in the light most favorable to the People, the evidence was legally sufficient and the verdict was not against the weight of the evidence. The issues raised by defendant concerning the testing methodology and conclusions of the police chemist raised issues of credibility that were properly placed before the jury, and we find no reason to disturb its determination (see, People v Bleakley, 69 N.Y.2d 490, 495). The chemist's conclusions were not invalidated by the failure to perform a qualitative analysis since there was no element of weight in the crime charged (Penal Law § 220.39; see, People v Diaz, 157 A.D.2d 531, lv denied 75 N.Y.2d 918; People v Rodriguez, 203 A.D.2d 92). Nor was it required that the present sample be compared against a known standard (People v Rolon, 172 A.D.2d 252, 253, lv denied 78 N.Y.2d 926).
